I have this ball for almost 2 years, and is one of my favorites.
Proshop driller, put me a standard leverage drilling, 16 lb, pin right near the ring finger, and cg out of grip, like 12:00. balance hole below the mid line near the pap.
i used polished because my type of release, and to get more Length in the lane, this drilling worked well for me, not the best but acceptable,
but one thig happened, i tried to get more power on the hitting contact, and i thought, closing the balance hole, the ball will take more positive side and resulting in more hook...
but what a mistake.... the ball loose te entering corner strongness, and turned in an unpredictable ball, i tried resurfacing but nothing, the ball was almost dead... then i decided to reopen the balance hole, this time a little below the original, and the ball became to life again...strong, predictable, forgiving, and a good choice for many different lanes.
well.. now i have learn the lesson... balance holes in this kind of balls refine the behavior of balls, and playing like me (mid-speed and strong revs)at medium dry lanes, are a good choice for getting more control and predictability.
