I drilled the one out in the ball I had, at least partially anyway. It fell out, but I use thumbsleeves anyway, so it just looked a little like a vent hole.
Shot a couple of good sets with that ball, including a 793 (dang tenpin), before I got rid of it, and the guy who bought it from me is still using it.
