i new when this ball came out that this ball wasnt going to do much.because of the urethane cover but still has a pretty strong core shape to it.When i drilled mine it gave me a nice controll but smooth reaction to the pocket.Even for when i was using it on the shorter lane patterns it didnt over react for me playing up the boards.

My Grenade is laid out with the pin drilled out in ring finger being place 3 inches from axis and cg being place in the center of my grip.Box finish is out of the box.For bowlers out there looking for something for dryer lane conditions after those long block tournaments or for the shorter sport patterns this is the ball i would use.
