TRUESIGHT! A revolution in cuesports! 

R Hopper A guy i play often only can see with 1 eye. I tell him he's cheating because it makes lining up the shot easier.

You don't need it cyclops.

+Chris Martin question? .... Why don't the pros have the same stick location when down on a shot? Some are to the left , some to the right , some dead center of the face ... why is that???

i dont think you really understand your own question. it really wasnt a question is why. be more specific.

It depends on their eye dominance. Usually, but not always, righthanded players are right eye dominant and align their cue under their right eye (like for example Earl The Pearl or Niels Feijen who by the way can only see with his right eye afaik) and vice versa (examples Scott Frost or Joshua Filler). Then there are righthanded players like e.g. Johnny Archer who is left eye dominant, lefthanded players like Jayson Shaw who is right eye dominant and some prefer to have it dead center under their chin which i think are the rarest. At the end I think it just comes down to personal preference.

I believe things like this could help a beginners learning curve.
