This ball is beast. Threw it first set in league today. playing abuot 15-7 on a mid to dry shot. This ball pushed down with ease. Not sure of exact drilling. It was a used ball, and the pin had already been drilled into. I'm a tweener who's statred to put more on the ball. Abuot 15-16 Mph. Usually i just find balls on racks and use em', but i decided to by the Spike. Now i'm usually playing straight up, and usually out to the gutter. Not the case here, more of an inside shot. Ball was grwat downt he lane, very predictable. i kewn when it owuld turn and how much it would turn, and when i was leavin' a 10. In the 3 game set i rolled today, i only missed the hole 2 times(one was a 2-6-9-10, other one was a 4-6) left 1 7 and 2 or 3 10's. Shot 233 267 255 (only 2 non strkies a game) for 755, which is apersonal best as long as the High Set in the league which ended today. This ball is definately a keeper in my bag.
