>>> I was curious to the que that Lau uses, "rotate hips while pulling the knob to the ball" I've tried it many ways and I've figured if you grip the bat lightly with the top hand, and you let the bottom hand "level out" before pulling, than it seems that Tht is created. I'll have to hear from Jack on this but, Can THt be created without a pull from the top hand rather letting the bottom hand level out from a near vertical position before pulling it through, your thoughts?

> After the back-elbow lowers to the batters side, the knob (and the bottom-hand) rotates around the top-hand. It is the pull from the rotating lead shoulder (through the lead-arm) that supplies the pull on the knob-end of the bat. The knob never moves linearly, it is constantly turning. Because at this point of the swing, the bottom-hand is arcing around the top-hand, I call it “bottom-hand-torque.” --- Note: As you know, torque is when forces from opposing directions cause the bat to rotate around a point (in this case, that point is the top-hand).

Jack,

You said that "The knob never moves linearly, it is constantly turning." Isn't this "whipping" the bat? Meaning that your hands stop a foot or so from the contact area and the bat head is "whipped" through the ball.

It seems to me that the bat, arms and hands are moving forward "linearly" and in the midist of all this upper body movement the hands turn over. Isn't that obvious becasue the hands start out near the back shoulder and end up behind the front shoulder?
Don't they have to move linearly to do that?

Regarding the hands turning over. It seems to me that the top hand will role over the bottom hand naturally. If fact, I think it would take a great effort to stop it. For power this natural movement is enhanced but putting extra preasure of the bottom hand and top hand to execuate the movement faster, therefore providing more power.
