In all fairness to pro shop operators everywhere, there is no such thing as a GENERIC DRILL. I have drilled pleanty of bowling balls with this type of layout for customers who cannot handle a hook set ball motion. I have found that this layout gives a bowler who cannot repeat shots, a very consistant motion through the lane, giving them the highest pocket potential. Without knowing what the driller was thinking, or dealing with, it isn't fair to jump to conclusions.
And by the way, I happen to be averaging 246 this summer with a label drill, no extra hole, "generic layout".
And for glenn9812, talk to your pro shop about what to expect out of a layout, and try to gain as much knowledge from him as you can to help your game.
Knowledge is power, and everyone can atain it.
