If it's a low top weight, the weight hole is not that big. it is to the right around the 3 o'clock position on the side of the ball. And yes, the pin is on the otherside of the ball. If the top weight is high, then it takes a lot of work to make the ball legal. I have one with a huge weight hole and it still needed more taken out of the middle finger to get it within specs. I don't put this drilling on everyuthing. I have it on my BW, and thinking about putting it on a BWP. Probably going with conventional full roller on No Mercy Beat'n. The Anger, I want to try a new layout I've never seen, but it was in the drilling instruction sheet. It has the pin around the 2 o'clock postion.
