>>> Yes, you assume the position to launch the bat. It's easier said then done, but when rotation is just starting all forward momentum is converted into rotational momentum. <<<

The longer and more forcible the stride, the greater the momentum that would be covered into rotational momentum. – Then why do so many of the top hitters use only a soft stride or no stride at all? Why wouldn’t all hitters find it more powerful to take more powerful strides if linear kinetic energy was converted into rotational energy?

Jack-

Isn't it because the ball is coming in between 90-100 mph?If you were to look at the most powerful slow pitch softball players you will see the longer stride you speak of.Many slow pitch guys that have taken thousands of cuts trying to find the most powerful swing arrive at a position with their feet closer together so they can take a longer stride.
