As a aiming method put 2 pennies about 1" apart on a piece celephane tape with a small target dot between them. Put another piece over the top to seal it. If the ball goes thru clean there will not be any noise or clicking. I am sure you could use quarters so the ball will not go thru. You could try placing this in the pocket opening to make it tighter. You will not be able to go off the facing with this. It would have to be a clean center pocket hit.
