Is usually not a complete drop ---the kind where people in the immediate area, after hearing the loud noise of the ball hitting the lane, are inclined to check if their dental work is intact.  But have been frequently losing control of the ball a fraction of a second before, or during the release.  Needless to say, it usually messes up the shot (Though there have been times where it somehow finds the pocket on it's own).

 

With my mainstream equipment, drilled 3+ years ago, this doesn't happen. With several balls bought, drilled, and recently plugged and supposedly matched to the earlier equipment, I lose my grip on the ball a minimum of 2-3 shots per game.

 

One ball was so bad that I finally took it in for a comparison and the driller says the ring finger's span is a bit longer than the source balls and that a longer span can result in trouble hanging on to the ball, so am having that ball fixed.  If it works, I have several balls that will need the same treatment.

 

Just curious as to your opinions about how much affect the ring finger has on release/delivery ---presuming the fit of the middle finger is correct.  In short... do you agree that shortening the ring finger's span would help in holding onto the ball all the way through the delivery?
