> Jack thanks for the thread. As a result, I have concluded that the top hand release is more effective for today's hitters for the point you noted with regard to the hitter standing away from the plate and producing the wider arc which maximizes around the 1st and 2nd base direction. In that instance as you stated the hitter would have to jerk his hands/wrists in order to keep both havds on the bat. As such I feel this could potentially collapse the swing especially if the hitter uses a jacknife or crouch position (in the case of George Brett or Tony Phillips.) But hitters who stand closer to the plate likey benefit more by keeping both hands on the bat (in the case of Darrell Evans or Lou Whitaker). And in my opinion, hitters who lack the swing strength of Mo Vaugn and David Ortiz lose power or have trouble keeping the inside pitch fair without keeping both hands on the bat (if the stand close to the plate).>

All,
Top hand release IMO is irrelevant to POINT OF CONTACT. Both Top and Bottom hands contribute in power hitting. If torque is introduced in the swing, and torque is two equal forces acting in opposite directions about an axis, than I conclude both top and bottom hands are responsible for ANY batted ball.
The upward swing is done by what the body's tilt and what the arms and hands maintain....the back elbow gets tucked to the batter's side as the lead shoulder pulls the lead elbow in a forward rotation. This action is producing early batspeed and also torque.
The angle of the bottom hand or elbow maintains across the chest and is adjusted on upright body position for high balls and crouched over for lower balls. The reason higher balls are usually home run balls is because most players keep that front elbow up so energy build up is properly transferred from the rotating body. For lower balls, batters have the tendancy to drop BOTH elbows and want to uppercut or scoop at the ball does not transfer energy build up the body has generated. See link below for same swing on different pitch locations.
