Who needs closed bridge anyway?

[SlickRick_PCS]

What do you mean by "veer over the cue ball?" I've never heard that term that I recall.

Woah! Didn't see the reply... been a long time (Aug. 8). I meant to look over with the fingers ("peek over"). Since I am used to touching my chin on the cue and use the open bridge more often than so, when I used a closed bridge, I would raise my head up like a couple of inches or so above the cue so that I could peek for the cue ball. Sorry about my wording .

...no matter what kind of cue I use, I always have the same deflection.

A closed bridge will reduce deflection.

With a really stiff cue, you will move the CB forward when hitting, so the CB has no chance to deflect away

...please give your opinion.

My opinion is that none of this is true (sorry).

... Recently I've heard two kind of theories to reduce deflection. The first one is the whippy shaft. The saft will deflect away, so it will reduce deflection on the CB (like 314/Z/etc). But there is also a second theory to reduce deflection. With a really stiff cue, you will move the CB forward when hitting, so the CB has no chance to deflect away (like mezz/meucci/etc)....

I think that if you want to understand squirt, you need to at least look over the conclusions in Ron Shepard's paper. See item 10 at http://www.sfbilliards.com/misc.htm which has an executive summary as the second link.

Have you ever tried to measure the pivot points of your sticks?

It doesn't really matters what you think is true or not. When I apply english with different kind of shafts, and the amount of deflection is always the same, it will be true to me. I see it with my own eyes. If you don't think it's true, just give your theory why it didn't changes the deflection? The second, if it's not true that a stiff cue can give reduce deflection, why are cuemakers like Mezz or Meucci making there shafts stronger/stiffer to reduce deflection?

Yes, I know squirt, and there will also be squirt on every hit. But that doesn't explain why the CB always ended at the same point. It must be really coincident that squirt and deflection always compensate enough so the CB ended at the same place.

No, I've never measure the pivot point. Do you have suggestions how to measure it?

It doesn't really matter what either one of us thinks is true.

When I apply english with different kind of shafts, and the amount of deflection is always the same, it will be true to me. I see it with my own eyes. If you don't think it's true, just give your theory why it didn't changes the deflection?

I can't account for what you think you're seeing - I'm not there. Have you tried to measure it? Your eyes can deceive you. I'd be willing to bet that you're fooling yourself one way or another.

The second, if it's not true that a stiff cue can give reduce deflection, why are cuemakers like Mezz or Meucci making there shafts stronger/stiffer to reduce deflection?

Where do they make that claim (I haven't heard it)? If they do make that claim you'll have to ask them why, but all the tests I've heard of show little or no effect on squirt from shaft stiffness.

So it must be a huge coincidence that everybody but you thinks different cues squirt different amounts. I mean, how did they all come to the wrong conclusion?

By the way, if all cues produce the same squirt for you, what makes you think stiffer cues squirt less?

Ok, I give you an example. I can consistenly make those balls, with always the same aiming point. I don't think the error margin is that big.

Actually, I don't know. I can consistenly make the same amount of squirt with any shaft. I believe there is squirt, I also believe that some cues like OB1/314/Z might give lesser squirt. But I've never make lesser squirt with any of those shafts.

By the way, if all cues produce the same squirt for you, what makes you think stiffer cues squirt less?

I don't think a stiffer cue will squirt less. But the only thing I know, is when using a closed bridge, the shaft will deflect lesser. May be, when I'm using a 314, the 314 has lesser space to deflect and will be a little stiffer, so the amount of squirt will be like equal as all the other shafts I used.


I haven't used a open bridge yet with a 314, perhaps I should try it, and see if it's reduce or gives more squirt.
