Re: hitting the ball to the opposite side of the feild
Jack describes the upper body engine well in his Final Arc. IMO the best oppo mechanics comes from Plane Transition ( bat more vertical moving to the 45 launch slot as the lower body lands the stride and the hips beging to rotate). This sets up the bat barrel to come square to the opposite field and still be in a rotational pattern. An extreme example would be Julio Franco( still), Gary Sheffield( with motion) and a not so extreme would be a careful look at Mr Elliott in the Final Arc swings as his bat goes more vertical and back to the launch slot.
Plane transition unquestionably adds unbelieveable power to the opposite gap/Maybe Jack can lift the fog here and/or associate it with THT , BHT and CHP.
