I just purchased my Big Bang R, from Allstar Bowling. It was drilled by Lou, the master of ball drilling and what a fit. This ball holds the line great, after the lanes breakdown. There's no over/under reactions, like in most high end balls we see today. My drilling is a stacked, weight hole on the side. This ball goes long, with a nice arc to the pocket. The pins explode, beyond my belief. I started to use this ball, when the Terminator was too much. First league game, 10 strikes, with two ten pins, just my luck.
In any case, if your looking for something, for when the lanes break down or on a medium shot, this is it.
Good bowling to all!
