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.
