I just had a TR2 Drilled up, Right Handed bowler, Drilled with pin below ring finger, by driller to get the action I wanted from bowling ball, ball speed 15+ stroker, Question I have, the track is over my finger holes, is this OK?, I don't hear any thumping of holes, is this something I should worry about? Any thoughts?

Brett, thanks for the feedback, I took back to my proshop, he re-weighed the ball, he added a weight hole, hopefully this will solve the problem. I will find out next time I go out.
