The weight you removed will be distributed among side weight, finger/thumb weight, and top/bottom weight. The sum of the changes in all three should be very close to the 2.4 oz the chart says you removed. -- JohnP
quote:g.....once you get past 1.5-2" of depth, all you're doing is removing total weight. Anything deeper than this is just to hit the core and remove mass from the core, changing core dynamics.Yes, to your question of drilling through an existing hole at an angle to remove more weight without changing the diameter of the existing hole. It is Legal. To get back to original question, why not try pin on VAL above PAP maybe two inches, cg on line to center of grip.I have an higher RG ball drilled like this. Good revs, length, easy turn.
