I'm doing some work with my arsenal. In a few weeks, my first three balls will be the Copperhead, Kinetic Energy, and Ultra Zone. I'm looking for a ball to fit at the end of my arsenal. I'm bowling mostly on sport patterns, so I'm trying to think which one will be weak enough, but not too weak. I throw 15-17 mph, low revs, usually playing outside or track area, but will move in if necessary.
