I know one thing, if I go to a different person to drill my ball, they all say that the other guy drilled it wrong, I've had many a time that after the ball was drilled it would lock up in my hand, I would try the shake the ball off and show them that it would not come off. To this day I have a problem with my ring finger, when I put my finger in, my thumb doesn't go straight into my thumbhole. I do still carry a 210 average, but really how hard is it to drill a ball that will properly fit a hand
