I used Mike Dechaine's OB shaft with a layered Kamui Soft on it, and right after I put it on I won my local tournament twice in a row, including one week where I lost 2 games (not sets, games) the whole night.

So clearly the layered fancy tips and LD shafts are as good :grin:

I would wait for more data than take a mere mortal's word. Because we all stroke, hit differently. They may look alike but they are not. If it's my wallet I spend $$ from low to up in price as I see and understand the proof. Not top to bottom. Streaming could help if they would announce type cue, tip type etc. They do it in Golf all the time.

Learn how to hit the ball, play inside and outside the cue ball.
If you can't do that just use a broomstick, a tip will not matter.

This one grabs too much, this one not enough, YIKES.

All these overpriced tips, the latest and greatest best thing that's going to change your life.
This tip made my game jump up a ball might be the funniest thing I have ever read in pool.
I am going to design a tip made out of Swamp Azz, guaranteed to make you lucky and your game jump 7 balls, move over Shane, Swamp Tip Azz Sheriff is in Town.

If Mosconi used a Kamui he would not have miscued on # 527, wait, he didn't miscue,
Buy one of those Dream Catchers and hang it on your case.

I have over 5000 fishing lures, 4999 catch the fishermen, and 1 catches the fish.

Find the tip you like and buy 2000 of them, if the formula changes or they close shop, you have the tip you love for life, or go buy 4999 fishing lures 1 at a time for 30 years.

I can miss with any tip

Good advice and facts. Mosconi just put his cue down and said that's enough or he'd still be going. Even if one were to buy 2000 tips you'd need to keep em in a vacuum to preserve. More important to find level of soft to hard needed tor one's comfort and confidence. Heard Tom Brady will bring out a soft layered pigskin Super Bowl.

And the God of Pool, Efren, uses a cheap assed Elk Master. End of discussion.

A Pro would play with Tasmanian Devil hide if he were paid to use it ! Some synthetic company is going to put the leather dudes out of business. tick tick tick........

Ft. Worth Texas is the best in the United States right now

-------------------------------------------------------------
CJ -- Very off-topic on my part, but just scratching my head wondering why anyone running "a break and run contest" would be nutty enough to allow you to enter? Seems like that would be like giving the $800 away, and pretty unfair to locals (unless in fact, many of the other entrants were pros like yourself).

Just curious. The reply is the teacher.

Arnaldo

Anyone can enter, I was at one with Jeremy Jones, Buddy Hall, Robert Clark, TJ Davis, Erman Bullard, Coy Lee, and several other top level players. You have to understand the level of play around Ft. Worth Texas is the best in the United States right now, there's 20 players that can play flawless matches, more if you include Dallas and it's suburbs.

Thanks for the reply, CJ, which really gives us a full view of the great (and enviable) circumstances in your area.

The synergistic game-elevating effect of so many high level players -- both pros, semi-pros, and plenty of regional champs -- in those competitions must be electric to witness.

Is it in the realm of possibility that videos of some of these events will occasionally appear on Youtube as happens with competitions in other regions of the country? I'm sure that many AZB-ers living far from Fort Worth would really enjoy seeing that exciting action. Sounds remarkable to behold, even when remotely spectating via computer or TV screen.

The dumbassery is strong earlier in the thread so I will leave that alone and address the idea of a synthetic replacing leather soon... It will happen... There is a reason Outsville starts with leather... Leather is perfect simply because of the way it performs under compression.... The way it follows certain laws is so completely minutely different than any existing synthetic base that we are still a fews years away....

I started this trip in the early 90s with future tips... 20 years later... Everyone is in the same spot.... or not... our first Synthetic comes out next month.... It's a break tip....

Regarding the largely unresolved question (in scientific terms) about the often-cited performance superiority of laminated tips versus traditional single-layer ones, a few years ago I contacted Jack H. Koehler who is renowned in pool circles for his scientific analysis and explanations about the physics of pool. He’s the best-selling author of “The Science of Pocket Billiards,” “Upscale Nine-Ball,” and
“Upscale One-Pocket” as well as more than 20 scientific papers on subjects unrelated to pool.

I thought he’d be the perfect man to understand and hopefully explain the physical mechanisms or science underlying the commonly discussed unique characteristics and superior performance of laminated cue tips compared to conventional non-layered tips. (Varied opinions continue of course in matters of "superiority" with more than a few players returning to conventional tips after trying laminated ones.)

Below is his then-emailed reply to me which contains his very creditable thoughts on layered tips (and which I thought would be interesting to share with fellow AB-ers
--------------------------------------------------------------
“Leather (from the donor animal) is not homogenous. The texture (and hardness) changes from the hair side to the inside. If the tip is made of one piece of leather, you get a simple progression from hard to soft. The thin pieces of leather skived for lamination purposes have these same characteristics but when you stack them, to get the proper thickness, the final product is much more homogeneous. The randomness of grain from layer to layer when compiling the stacks, which you properly mention, probably also plays a part in the resulting superiority and performance characteristics.”
---------------------------------------------------------------
I think that, as usual and as expected, he got right to the heart of the matter.

I would add that the nature of the adhesive (and the process) involved in lamination also affect the often discussed pros and cons of performance when comparing the two overall categories (laminated vs. single-layered) with respect to "grab", glazing, mushrooming, longevity, change in hardness over time, chalk retention, etc.

Arnaldo
First. Thanks for Dr Kohler's thoughts on this.

I would add that this is a simplistic look at the subject though. And, I would be surprised if he said didn't say something similar. As previously mentioned, you must add milk duds and other chemical processes that virtually every tip is treated with today. Also, thickness of layers and type of leather. And, as you mentioned, adhesives. I would also add how the tip is packaged and transported (air tight?, extreme humidity, extreme weather - like shipping during extreme cold or hot weather). How your cue repairman treats your tip (does he apply too much heat while trimming or burnishing the tip, is his glue fresh, does he saturate the tip with glue to seal tip prior to applyication, does he store tips in controlled surroundings). There are so many variables that can alter your tip's performance.

It seems to me that this would be inevitable. But the fact that it's taken 20 years is not surprising. So many variables in dealing with tips. And all the individual preferences among pool players (and many who hate change). Not to mention a really small market with mostly cheapskates, like myself. Oh yeah, and now China knockoffs certainly around the corner. Good luck with this, but I'm not envious of your journey ahead.

I don't care what anyone says about layered tips vs whatever.

The Ki tech medium that I switched to from a layered tip plays consistent and doesn't overspin the rock.

The layered tips just grab too much.

My game went up a ball by switching back. But not just to any tip.

The ki tech medium.

They are the Nutz. They set a completely new standard in tips and I've played with them all. No way anyone could have an educated opinion without first trying them

A friend and I tested tips along with shafts to see how much spin a particular combination gets. Between the two of us we had maybe 6 different tip/shaft combos.

With a standard shaft and one peice tip, we were both getting to about A spot with the cueball, with a laminted tip and a LD shaft (his Predator 314-2) we got to B which was the most spin we could get, a few times we were able to get to the short rail not even touching the side with an LD shaft and laminated tip. A laminated tip with standard shaft and a LD shaft with a regular tip were in the middle of those, roughly in the same areas. I don't remember the exact ball positions but that was the test we played around with, use low right and see how far up-table we can swing the cueball to. We both shot with each combination 3-4-5 times and the area we could get to was consisten in all the tries.

The only way that this test will work at all is if you are able to do 6 things. Place the cue ball(1) and object ball(2) at the exact same place every time. You have to hit the OB to the exact same point in the pocket every time(3). You also have to hit the shot with the same speed every time(4). You also have to hit the same place on the cue ball every time(5). You also need to make sure that the balls are fully cleaned between each shot(6).

If anyone of these steps is not the same for each attempt then the results for the test are invalid.

What you are testing is far more complicated that you are making it out to be.

Only a robot could accomplish this test.

While the test conditions you describe and the use of a robot would be better, real world testing is valid. The more variables that are introduced into any test increases the number of repetitions that are needed to be confident of the primary result you are trying to understand. Dr. Dave studies cue ball squirt for 4 different tip types using 3 people and 5-7 repetitions (http://billiards.colostate.edu/normal_videos/new/NVD-15.htm). Based on the little we know, the test conditions cited by hang-the-9 for this test do not support much/any confidence in their conclusions. But I admire their desire to answer this question to their own level of satisfaction by performing tests rather than to rely on rumor, lore, gossip, or the scientific expertise of most pool players. Apparently, they did not feel a need to perform more testing to make their own choices.

Yes, the shot they chose has way too many variables to control: exactly how you hit the CB being the main one.

But I admire their desire to answer this question to their own level of satisfaction by performing tests rather than to rely on rumor, lore, gossip, or the scientific expertise of most pool players.
Me too.

Fine by me, but readers should understand they're not making truly informed choices.

I also like Ki-tech tips. I've tried the ultraskins, Kamuis, Tiger, Zan, etc.

I prefer Ki-tech. Therefore I will continue to play with them. I encourage the rest of you to play with what works for you.

As far as spin application, I don't understand why people use so much sidespin. Learn to play better position while staying closer to centerball. Or maybe people would rather spend their time arguing on here over silly bullsh*t instead of putting hours into practice.

Sorry...robots don't shoot pool. Pool shooters can tell the difference.
This is not debatable. If you shoot pool, you know the difference.

Okay...if you suck at pool then you just don't know.

Common sense is a great thing to have.:smile:

You're right, robots don't play pool. But then again, they're not supposed to either.

I agree that pool players can definitely tell the difference between tips, I would also have to question if what they see as the difference comes strictly from it being layered or not. Since there are no 2 tips, one being layered and one not, that are supposed to be exactly they same I think it would be impossible to tell.

Here's what I do know.

I know players who swear they get better spin or control or whatever with regular tips.
I also know players who make the same claim about layered tips.

Both are right, when it comes to themselves, and both are wrong when it comes to everyone else.

From my personal experience, I don't see any specific performance or playing characteristic difference based solely on whether a tip is layered or not. I certainly haven't tried them all, but I do get plenty of tips sent my way, and I am a pool player. Have been for more than 20 years. How much more I'm just not sayin! lol.

We choose layerd tips as the standard for our cue shafts because they are certainly more consistent from tip to tip. We have far fewer "bad" tips which saves us the time of having to cut them off and put another one on. We pay quite a bit more for layered tips than we would if we used the typical regulars like LePro or Triangle, but the time savings far out weight the savings.

What it all boils down to is play with what you like, and let the next guy do the same.

This part is for anyone and everyone who cares to read it. It's not specifically for you, poolguy, but it could be if you so choose.

It's perfectly fine that we all have different preferences. Our differences only become a problem when we try to impose them on others. If we look at all the "discussion" threads that seem to get out of control, they usually all come back to the same thing. Some of us, if not most of us, seem to feel like the world should see things our way. We are afraid that if the other guy thinks different then others who read the thread might believe him instead of us. It doesn't matter. The readers here, and anywhere for that matter, will make up their own mind. Trying different things to see what we like and don't like is a big part of the fun anyway. It's like a discovery, or treasure hunt.

Me personally, I like to see what others think about different things. It doesn't mean I'm going to change, but it might!

another thing... no 2 players have the same stroke, either. I've seen my cue behave completely differently in the hands of other players, and I'm sure I'm not the only one who's experienced this.
