I'd have thought that change in velocity of a ball was directly related to the rate of change of momentum, and that mass at impact point was the key to effecting this most efficiently, therefore a larger mass of bat, effected by whatever means you have, over the impat area with the ball would give you a greater rebound velocity. The laminate bat gives you the ability to increase the "contact mass" or effectively increase the sweet spot area by allowing more mass per area, or maybe I'm just starting to go mad!?!?
Nope
Does anyone knock in the edges right at the top of the bat, in the stickered up area?
