You state that there is no pivotal axis. VJ Trolio writes about a downswing pivotal axis located in the region of the left leg in his book on Hogan, and he states that the pelvic rotation angular momentum is enhanced if the COG is nearer to the pivotal axis. Are you saying that his idea about a left leg pivotal axis is wrong-headed?

Secondly, during the downswing-followthrough-finish part of the swing, the pelvis rotates 135 degrees (presuming a 45 degree pelvic rotation in the backswing). I personally believe that the pelvis essentially has to pivot over the straightening (firming up) left leg, and that it is impossible to pivot over the right leg, which is becoming progressively more unweighted during this time period. Are you saying that I am wrong to think in this manner?

Here is a video link to Shawn Clement hitting off one-leg.



I believe that he is pivoting over that left leg during the downswing/followthrough. Do you disagree?

Jeff.
