Dave,
This ball is not drilled correctly, at least if you want it to hook it's not. It looks like it should be for a lefty, but the weight hole is for a righty.
This drilling is an end over end roll drilling that won't hook unless you really turn the ball. It'll work good on drier lanes with dry heads and dry backends, but that's about it.
I'm sure that's not what you wanted it for. But, maybe I'm wrong. =:^D
