While at the BSACA we conducted a test of deflection on a standard maple shaft, a Meucci shaft, the Predator 314 and the Predator Z shaft. The results were simply amazing!
Starting with CB at foot end center spot, applying 1 tip of side spin, with a 2 speed shot (average speed), aiming straight down table. After each shaft, Meucci- Standard- 314- and ending with the Z shaft, we marked the rail where the CB contacted it. We then performed the same test, but with a 9 speed (typical break speed). Each shaft made 3 hits to get an average position.

Shaft deflection at 2 speed: (chalks= used for measuring)
Meucci- 2.5 chalks
Standard- 1.5 chalks
314- 1 chalks
Z-.5

By seeing this, I can agree that the Meucci has a LOT of deflection, the standard shafts have some deflection, the 314 has very little, and the Z shaft has hardly any at all. So, when you're taking the long shots and your over cutting the ball, it's most likely not your aiming, but the shaft deflection!
Just something I found interesting and wanted to share!

this "pool god" i have around here says the Predator Shafts are a joke, a gimmick, and that pros only endorse them because they get paid to play with them.

of course, this is the same clown that tells me Bob Byrne doesnt know sh-t, that he's somebody around here, thats never played in a big time professional tournament, that claims to know nancy/gordon hart, that says all production cues should be used for roasting hot dogs, that the pockets on Olhausen tables arent any good, and so forth and so on.

thanks Zim, i was seriously thinking about getting a Predator for my Lucasi, and you've pretty much cemented the idea in my head.

My first cue was a Dufferin, then a McDermott, then a Prather custom cue with a 314 shaft. WOW! The 314 was really an improvement. The about a year and a half ago, I got another custom cue and started to use the standard shafts again and they felt fine. About 2 months ago, I cleaned up the 314 and put it back on the Prather cue and took a few shots...what a terrible feeling I had. I used an Espiritu with the 314 shaft for my Instructor Course at the BSACA. The standard maple shafts DON'T stand a chance against a 314 or a Z shaft by Predator. Not all pros use Predator cues, but most use Predator technology, the 314 or Z shafts.
Who ever says Meucci has no deflection is crazy!!

Zim,
I have obtained similar results in the past (before the Z-shaft was available). I have used a 314 for 2 years and always thought I would stay with it until recently. My ferrule was cracking so I returned the shaft to Predator for a new ferrule, and bought a replacement shaft at the same time (both shafts are 1" longer than standard). When my old shaft was returned, it had a huge bend in it, I returned it again and they tried to fix it, but it still has a small curve to it. I then checked out the new shaft and it also has a small curve to it. I am in the process of returning the new one to see if they will fix or replace it. The interesting thing is that I told all of this to the local billiard supply store manager, and he reports that he and a friend have 6 Predator standard shafts between them - and only one is dead straight (and he believes that warping is a common problem with Predator shafts, even though that is what they are supposed to be designed to minimize). I understand the principle of acceptable tolerances, but only 1 of our 8 shafts is playable (seems unacceptable to me).

My question is, do other people also have this problem?? Maybe Rocky will check this thread and weigh in with an opinion. I love the way the shaft plays, but if I can't find one that will stay straight I'm looking elsewhere. I would definitely check any Predator for straightness before paying anyone for it (DCP are you listening).
 
Hello Zim!

I am new here and my name is James. Are still using the Dominator shaft. And have you done any test on it. Reason is I am not sure if I want to stop over to Steve Dominiak Place in Stafford NY to check everything out and possibly test drive some of his cues. But I would like to only get the shaft and this can change with the butt and joint of the cue.

James.

I have a bit of experience with different cues and this topic.

Started with a Meucci, then a Schuler with the Euro taper 9-ball shaft, and the 3C stiff shaft with small ferrule, then a Richard Black cue and added a Predator 314 shaft to that cue.

What I recall from the "Jacksonville Tapes" of the mid-late '90's, discussed on rec.sport.billiards (high-speed film of various deflection experiments conducted by among others Bob Jewitt, a college champion, smart guy, scientist, and Byrne's technical consultant) was that the critical factor was mass at the tip end of the cue. For example, a lead fishing weight soldered into the tip in the last 6 inches deflected or pushed the cue ball offline using sidespin much more than same-weight (e.g. 18-oz) cues lightening the tip end for example using shorter ferrules (Schuler) drilled holes (Predator 314) etc. I can't speak to the Z shaft, but presume it is a Predator improvement in this vein along the 314 lines.

Ultimately it really doesn't matter, so long as you "Know Your Cue and Stroke". My aiming point on the object ball using maximum or less sidespin with my cue will lead me to a different aiming point than yours, though you can take my advice as a starting point, but YOU have to do the same shot (speed, power, focusing on deflection amount) enough times to KNOW what is going to happen for you. Nothing more and nothing less. Do your homework, don't whinge about brands because brands won't turn a C player into a B or an A into a pro, whereas really hard work on first large then smaller details (and back to rethink the large to clarify your approach to the small) as you travel along the refining/making important distinctions amongst almost, yet different shot, learning curves will. The finer your distinctions the more precise you can play whitey, and that is the easier game in a nutshell.

Try the maximum spin off the bottom cushion shot, placing the cue on the foot spot, object ball on the middle diamond head rail. With my Schuler, I think I remember I need to aim just a bit over 3/4 ball to the right using max left spin to miss the ball into the cushion and spin it in, whereas with the Predator it is more like aiming a half-ball right to hit it on the nose. Jacking up on the end rail first diamond left of the corner to hit a ball on the end rail one diamond right of the pocket, I must aim two balls right of the object ball, allowing for curve. Sometimes I can cut it in, other times safe. Nasty shot, not nice of opponent to see you hate it and give it to you twice in a row in a short race. I now "know" how to deal with this problem, and hope to surprise him next tournament with success.(lucky my ass, I took this shot home and gave it 45 minutes or more work to achieve resulting acceptable pocket/safety chances!)

More critical than that one shot is to place a ball in the corner pocket, use maximum side spin, and realize you need to aim to miss the ball entirely, relying on the deflection from sidespin to take you into the ball thin, 1/4, 1/3, 1/2 etc. Or the similar shot when the ball is above the pocket of using high inside english to spin 3 cushion around, from the other end of the table. Over 6 diamonds, how much do YOU need to allow for deflection for inside or outside english, with a given speed of stroke and tip offset? I know, for me, and my cues. Do you? What about 8 diamonds, 4 diamonds, 2 and 3/4 away? can you easily factor in the aiming adjustment once you decide on the shape of the shot before you get down? Once you are down on the shot, if you change your mind and adjust the sidespin, do you miss the shot badly? You know your cue, now know enough to get up and re-aim factoring this in new because _EVERYTHING_ about the shot has changed, two inches to the left or right, high and low. Time to rethink, and re-aim.

The Predator is nice because the amount deflected is less, making it easier to calculate for me. But any player with any cue can learn these things too, so in the end the advantage is neutralized, so do you allow larger margins for your existing equipment, or pay cash and then learn to work with the improved tech? Either way works, really, the Predator way costs $200 more. It was worth it to me, but you might have better uses at your stage of life for that $200 spent than me. It depends, and Earl Strickland or other top players could probably pick up a Mop handle and figure it out in less than 10 minutes too, I would guess. Maybe me, too... learning to adjust to "local conditions" is more critically important than whining about "back on my home table I could do this..."

I do know one thing, for sure. The Predator absolutely sucks as a jump, curve, or Masse cue, that soft tip end so nice on level shots sucks big green ones when trying "interesting shots" whereas the stiff Ray Schuler cue is a dependable true champ in those cases, and that is a fact.

May you know your cues, deflection, aiming adjustments, and the best way to deal with certain nasty shots. Kevin

In the interest of completeness, I had a large post but didnt' really address three other topics raised, I would like to address them now.

First, easiest, Dominiak cues: don't know a thing about them. sorry, not good nor bad.
Second, Predator 314 warping: I have an experience of one: straight. The cues are built of 8 separate pieces, the hope is they are stable and stay straight, I say so in my case, but you say you have eight shafts only one of which is straight... I'm happy, you are not, hope you are fair to the product of which I am 100% happy.

Pool Gods: have clay feet, used to play 10 times better than anyone else, nowadays their eyes are shot, the balls/cues/cloth players are shitty, ultimately they were great and took the cheese back when but nowadays are sometimes. Well. Enjoy the stories, take them with a grain of salt, it all may be true, but then again, the competition YOU are facing today, and the table layout, can you if you execute well run out, is the main point. Stay focused, get out, and perhaps one day the old pool god will be saying "I knew him as a champion as a sprout, taught him all I knew, just look at him now!" Most people only remember the good times, just ask gamblers about their wins, then their losses... Self-delusion about your actual ablities is the key losing attribute to pool players. Champions say "I didn't execute well" (my fault) Losers tend to say (He got the rolls... he.... [any excuse but their own mistakes]).

"Former pool gods" that tend to bad-mouth others more famous... are often trying to "build their own credibility/legend" less through actual achievements than by the tactic of down-grading others. Not always, but a starting point for your evaluation of the credibility of the source of such claims. Reports of other players greatness are always tinged with the range of outright lies to honest reporters mispercieving the actual event.


how many times out of 10 do you get out? Really. Not your best days in stroke. Try Bowliards, 10-ball break, 10 straight runout is a strike, missing one as a spare, scored like bowling... less than 40 a beginner, more than 40 a C player, more than 140 a B player, more than 200 an A player..

There are a lot of different ranking systems for handicaps, just try one and if you turn out weak address the problem (your weaknesses) rather than become the old pool god ( I wuz great back then). Pool is rough, you do or you die, age is not the matter, it is performance in this event.

I am happy to be doing well these days, 6th in Kanagawa prefecture in Japan out of 10 million people, as a B player... somedays I shoot straight, other days my safeties pay off... I can win on a bad day if my opponent makes one more mistake than me...

I have plans to conduct same test with the standard maple, 314 and Dominator shafts. I'll post results soon! I'm currently playing with my Dominiak cue with Dominator shaft (as of 2 weeks ago, new league session). The Dominiak butts are beautiful, minor flaws in the B grade shaft, but still plays well.

Thanks,
Zim

Zimmer, Here we go again.
Please explain,
WHAT ARE YOU TALKING ABOUT SHAFT DEFLECTION, OR COMPLETE CUE DEFLECTION??

Zimmer, did you use a robot or some jig to swing the cue the same distance with all shafts, hitting the ball with the same speed,and did you use the same butt with all of the differant shafts.
[You are refering to shaft deflection, as stated above].

If you didn't, these test mean nothing, and are not a true test of [as you say] shaft deflection..

In order to come with a postive test for shafts, [my way of thinking], you need to use the same butt with all shafts. The joint needs to be the same. The weight of the complete cue [with any of these shafts] , needs to weight out the same. The same type of tip. The joint configuration, size, and materials, will change how the shaft re-acts to stricking the cue ball.Therefore, you wind up with way differant results.

There will be a huge differance using the same butt with all shafts adapted to the same butt..

If none of this was done, the test are not complete and or fair testing. If we test, do it the right way. Use the same jig for all and the same butt for all.


Anyone who thinks that the butt does not make a differance,needs to re-think it. All componants of the cue, makes a huge differance in the end results of this type of test. [ INCLUDING THE GUY HOLDING THE CUE].

Your test was simple and is a good one, and would be a better one for comparison, if all shafts were used on the same butt.This would be a true test of "shaft deflection".


TESTING of CUES!
For cues, comparing one to another with solid maple shafts, Z's, or laminated, that's a whole differant bag. Then you would be comparing one "COMPLETE" cue to another.[ not just a shaft].

Any of the test that I have seen, was not a test of shaft deflection, it was a complete test of "cue deflection".


Of course the player who is the real test. What he likes and dis-likes.
Just adjust to whatever, just like a fast cloth, as to a slow one, adjustments........

COLIN, please leave this one alone.

The bus pulls up to the Predator convention hall once again. I don't know if everybody gets to see a certain commercial on T.V. in all locations throughout the country, but it's for 6 Flags amusement park. This multi-colored brightly painted bus pulls up and a 90 year old man with big glasses steps off somewhat feebly and hesitatively. He looks around somewhat confused and then upbeat music starts playing and suddenly he starts dancing with his arms and legs going all over the place at warp speed. He ends up at 6 flags amusement park on all of the roller coasters and rides with herds of people following him around as if he were the pied piper. It's a great commercial and one of the biggest hits on T.V. This whole scene that I described reminds me of what happens everytime the Predator bus pulls up loaded with all of the hyped up frenetic partygoers that want to dance in unison to the Predator song. The two magic words of "deflection" and "spin" are enough to make all of the groupies jump up and start their testimonials as if it were a revival meeting and 6 Flags rolled into one. Arms are waving, feet are dancing, legs are everywhere, and the singing is at a fever pitch. I love it.

The damdest thing though, is everyone keeps coming up with different deflection results. We have Zim whacking balls around and coming up with his results measured in chalk cubes. We then have Platinum billiards doing their tests with a robot and posting results that the RSB scientists like Jewett, Shepard, and the rest of the gang saying that these are false readings based on THEIR results of pivot point testing that they've done by hand. That having been said, all it takes is for different individuals to do a pivot point test by shooting the CB and you have a different result for each one. And then you have another RSB nitwit that is held in high esteem there who built his own jig to test deflection and his results came back a lot higher for ALL cues, even a Predator, as well as a custom built shaft with a conical taper and 10mm tip. Then we have Bob Meucci who has his results and everyone jumps on his ass and says that he's a liar and the entire test is invalid, even though his test is the only one that's on tape and done in the most controlled fashion. Bottom line is there's no test results that are even close to each other and no real correlation as to what really goes on when you're playing on the table with different speeds which are usually much slower, pivoting your cue with backhand, speed of cloth, or other factors.

Kevin was correct...you just gotta know your cue. Blud was also correct, but what does he know, all of his cues have a Bludworth shaft and that's what he's trying to sell, plus he's only been in the cue making business for less than a year...right?? :rolleyes:
 
I wonder if the robot used knows tuck and roll, backhand english or slip stroke. :)
I am not shocked by the results Zim posted though.
I've shot with a Red Dot shaft one time and I could not believe my eyes.
The cb deflected, or squirted as some would call it, almost a full ball.
I hope you can elaborate more on the method of testing Zim.
You didn't mention what size table was used, tip and speed in terms of number of rails hit.
 
yep

Willee, I'm sorry to hear about your ongoing problem with the Predator shaft.
But I, Drivermaker...like George Washington (not to be confused with Bill Clinton) cannot tell a lie...I am the owner of a Predator shaft which is 4+ years old and has been put through the practice and playing wars. (not something I am ready and willing to admit since you know my stance). I put it on the butt that it was fit for after reading your post and the thing is as straight and as pure as the day it was purchased and I must say is absolutely perfect, I mean perfectly straight. That having been said, I hope they screw you in order that you can test some other shafts and just see what you've been missing. Little things like feel, touch, sound, balance and other intrinsic factors. Good luck................
 
The funny thing is, is nobody has commented on another factor in all of this.

The wood.

Each piece of wood is a little different, it's going to play a little different, how it was seasoned (or not) needs to be taken into account, whether it was dipped in chemical stabilizers (or not).

Blud's test, while being the most accurate, does not take into account, the wood. While one batch of shafts might produce a result of predator deflecting the least, another might show Schuler deflecting the least. They are all going to be a wee bit different....it won't be consistent from shaft to shaft.

I'm sure Blud will concur, while he strives for consistency, it is simply no attainable using products made by nature. Every cue maker has his own little "tests" for determinig what shafts are going to be good or not, whether it's the miracle 4 oz. mark, bouncing it on a concrete floor, measure how far the shaft bends when a 1 pound weight is hanging off the end...whatever. But it's all just flim flam....none of it takes into account cell wall structure of the wood, how much cellulose is left in between the wood grains...etc.

Of course Bob Meucci came out on top in Meucci's test....he didn't go back, and randomly pick any old Meucci shaft off the wall, I guarantee that he did some serious testing of shafts before hand in order to pick out the shaft that was going to put him on top....Predator too.....none of these companies did test on 500 shafts of 5 brands, they did it off of one shaft of 5 brands....incomplete results, in any scientific area.

What it all comes down too, is there is NO WAY a cuemaker can determine how much a shaft will deflect (and I hope I'm not around when the art of cuemaking gets degraded to the point of making completely perfect non deflecting cues....if that happens, every cuemaker will have a 10 year wait). And, what deflects for me, may not deflect for Zim, but might deflect only a little for Blud....

I don't worry about deflection...plain and simple...I've found the cue that works for me, and I've put in the hours necessary to know exactly how my cue should play.

The best advice I've ever heard about pool (and it is very applicable to deflection) came from Steve Davis (one of the greatest ball pocketers that has ever lived), somebody asked Davis "How'd you make that shot?", Davis responded with "No, no, no....you go to the pool table tonight, and shoot that shot 500 times, and come back here tomorrow and tell me how you would have made the shot to get the same outcome."

Everybody is different. Every cue is different. Every shaft is different. Every stroke is different. It's what makes humans so amazing, and one of the resons why we play this game, and keep coming back everyday. If every cue had no deflection, and we all had strokes like Mike Massey, and could cut the numbers off the ball like Steve Davis, kick & bank like Efren...nobody would play pool, because it would be to easy.

Enjoy the game, and play because you love it.....but while you're loving it, learn something about what you're doing.

I step down from my longwinded soap box.

D'maker,
Thanks for the feedback. It just SUCKS having to twirl your cue each shot to find the plane of the cue that is straight. If they don't fix it I'm going to have a custom built (I've been thinking of Blud and Jacoby) - any suggestions (money is no object as long as it's straight).

Pigcarver,
Nice story about Steve. A similar story about Jeanette Lee - at a pool lesson a student asked her about her statement in her book that if she missed a shot in a game, she would set up and shoot that shot 100 times in her next practice session. She replied, "I don't do that any more... now I shoot it 400 times." I've tried it, but my head starts to hurt at about 30 or 40 repetitions.

Bob Meucci has set up his stroke machine and tested hundreds of shafts at many pool events. Just walk up and hand him your shaft and he will test it right then and there. Very few shafts will show a low squirt as his. Some will come close ... others will be way off. Meucci shafts show the lowest deflection on the Meucci machine. That is not hard to understand. If you build a machine then make shafts that give the lowest squirt as measured by it, are you really measuring squirt or have you just adjusted your shafts for the desired outcome on THAT machine. I would seem odd that Predator also made a stroke machine to test squirt and thier shafts test best on it. I doubt either one did that intentionaly but really tried to make a machine that would give an honest and repeatable measurment of squirt. I think they need a machine to test the machines. <grin> How about the MYTH BUSTERS taking on this one?
 
Blud- The same speed, distance, stroke were all used. However, yes, you are correct- all shafts had LePro's, except the Z, it had a Moori tip. We did a simple test with the tools we had and came up with these results. Yes, wood has variations and no 2 shafts are going to be 100% the same, thus have a slightly different outcome for each shaft. I don't have a Bludworth shaft to conduct tests with, so I can't say how it would deflect.

When I mentioned deflection, I am referring to the bend in the shaft upon contacting the CB. While the CB is traveling to it's destination it has a certain amount of squirt (go off of aim line) on it, causing it to contact the rail in a different location (measured by chalk cubes).

Obviously this is not a 100% accurate test; however, it does give indication of the deflection and squirt caused by each shaft. Will I play with a Predator shaft 100% of the time, NO; am I more aware of why I'm over cutting long cut shots, YES; will I be able to compensate for the deflection and squirt, YES!
