hcw,

Great job on these posts! Bottom line is that Pivot Lag is very important in powerful shots. Pivot Lag cannot be FULLY realized as a lower body reaction to upper body movements. You can unwind the shoulders and sling the left arm and get SOME Pivot Lag, but the ultimate is obtained by the hips preceding the shoulders. The most powerful tour players wear steel spikes and twist the hips against the ground.

That which has rotated to the right on the backswing - in order only to allow the correct positioning of the arms/club at the top - HAS to rotate, or clear, to the left in order for the arms to bring the club down out and through the ball with force generated by the arms.

Spikes are worn to allow the player maximum purchase on the ground where resistance to the downswing force is at its greatest; NOT as some sort of aid to phantom power generation.

Consider, === as the hip plane and / as the clubshaft plane and then explain how the horizontal plane, rotary, shifting of the former can initiate the inclined plane downward motion of the latter.
