Thank you for your explanation on the benefits of rotational mechanics. Can you expain benefits of other type mechanics. Particularly how they relate to sweetspot velocities.

This is not efficient because momentum in the handle will not contribute to ball speed after contact with the sweet spot. Thus, energy used to accelerate the handle will necessarily deprive acceleration of the barrel sweet spot.

Thanks again Mike. During rotational mechanics, how many forces do you think are acting on the bat? (excluding gravity,wind res)
thanks, Kevin
