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.

Kevin,

There are numerous forces acting simultaneously during a swing. All these forces culminate in two basic areas of net force application - left hand and right hand, as these are the only points of contact with the bat.

One should use all available muscle power at properly timed intervals such that net force delivered through the hands to the bat is highest before contact with the ball. Since legs are further than shoulders from the point of application on the bat, leg muscles should be employed before shoulder muscles in swing motion. This will allow time for the leg force to propogate through the torso to the hands and will maximize the combined power of legs and shoulders at the bat contact point (hands).

Mike.
