Everyone uses an aiming system.
For most people it is a combination of different systems that they mold into their own.
It would be impossible to play pool without an aiming system.
Type of aiming used is dependent on the shot, because some shots just work better with certain ways of visualizing.
Like it was said:
Lots of people have problems with outrageous claims of the believers.
Some people don’t want to see the fellow players getting ripped off.
There is no magic bullet. If you cannot deliver the cue straight no system is going to help you.
Finally. JB always gets the last word and if you don’t see his way he will shout at you until you do or you just give up.
If you are wrong then I won't allow the last word to be the wrong information. If you are right then I concede and call it a day.
On Stan Shuffet's DVD he says that in order to work the system it is understood that the user has a reasonable proficiency and a straight stroke.
No aiming system yeasayer has ever said that an aiming system compensates for a crooked stroke.
On the contrary it amplifies a bad stroke because being on the right line means that any steering will cause the cueball to go off line and hit the object ball in the wrong spot.
So an aiming system that works forces the student to adopt a straighter stroke. And this was my personal experience earlier this year. I was playing pretty good with the system I am using but I decided I needed som help to get my stoke back. So I went to a coach and he did help me and now me stroke is much better, smoother and more consistent. That plus system means nice clean run outs for me.
In order for someone to get ripped off they would have to be deliberately mislead and sold something that has absolutely no value. The value is what's in debate. Simply claiming something is bogus is not enough if you don't have proof. So that's a big part of the issue as I see it.
I can agree with Mayoshi, if something is claimed to be mathematically provable then the claimant OUGHT to be able to do so.
Otherwise though I don't see any claims that the yeasayers have made which are unfounded and unbelievable to the point that the naysayers have the right to call them delusional. Show an outrageous claim that can be disproven. (and regarding the math, there has been PLENTY of math tossed out there by the mathematicians on this forum on the side of aiming systems. I confess that I understand pretty much none of it)
