> These features-more off plate,more separation,longer radius create a higher load/resistance to rotation may translate to a potential for higher maximum batspeed at contact but at the expense of swing quickness (longer duration and path of swing from "launch" of bathead-after knob pulling has finished-to contact) which means higher swing timing error. The difference in quickness is not very great, under a frame at 30 frames per second, but still significant.

This is a fascinating discussion. Great stuff!!

Tom, my view of the A-Rod and Aaron videos seems to show a different sort of swing to that taught by Mankin and Epstein. Is that your take??

Whereas Griffey Jr. seems to have a swing similar to Mankin and Epstein. Is that your take??

thanks
