I have a friend who wanted to buy a Gravity Shift and we saw one in the pro shop. The Gravity Shift has a 4inch pin.
We talked to the pro shop owner, saying that we would like to have it drilled with layout 1 indicated in the drilling sheet. After taking my friends measurement and doing some marking on the ball, he said that it can't be done because the cg will end up about an inch below the thumb hole which is not too good but he didn't explain why.
My friend really wanted the ball so he listened to the proshop owner and have the ball drilled with layout 2 but pin about an inch above his ring finger.
He bowled with the ball for about 2 games and find that it is going too long for his liking, sometimes missing the breakpoint. He was rather sad...this is the first time he try out a storm ball.
Sorry for such a long post...my question is it possible help my friend to reduce the length of travel of the ball ? And can anyone explain what the pro shop owner mention not to good to have the cg below the thumb hole ?
Thanks for reading and thanks for the advice...
