WHOA -- If I'm reading Rob816's description of the ball specs and the layout, the issue that might require a balance hole is side weight, NOT finger/thumb weight. With the pin located "right next to the upper right corner of my ring finger" (which, by the way, introduces another problem - it voids the warranty if the pin to finger hole distance isn't at least 1"), 2.2 oz of initial top weight and 2.5 - 3" pin out distance, the cg will be close enough to the midline (for anything except an extremely long span) to make the ball legal from a finger/thumb weight standpoint. But from the description, the cg will be kicked out 1 - 1.5" from the center line. This may or may not be legal. If that's how you want the ball drilled, do it, then weigh it. If it's not legal, go ahead and throw it enough to evaluate the reaction, then let your ball driller determine the location of the balance hole to tweak the reaction for you. From what he's told you, I suspect he is plenty competent to do so. Good luck, and let us know how it turns out. -- JohnP
