It has been years since I have drilled any guts into a pancake blocked ball, and don't remember some of the older layout techniques. Anyone who remembers cg and weight hole placements please chime in and remind me of some of the different layouts. I vaguely remember liking a ball with a weighthole like 9 inches from the grip center, but I can't remember the specifics. I'm just looking for some layout options for a plastic ball tournament I'm bowling in a few weeks.
