[Yoda]

As a side-issue, Yoda states in his Alignment Golf DVD that one should center the head between the feet at address, and then acquire rightwards spinal tilt by shifting the pelvis left-laterally. Hogan doesn't do that - you can see that his head is behind the center of his stance at address. He also moves his head ahead of that center line during the downswing.

Jeff,

What I advise is that golfers work diligently to acquire a stable Pivot Center, either the Head (2-0) or Point-Between-the-Shoulders (Glossary). Homer Kelley recommended the Head Center but did not mandate it (2-H). The Head 'Centered between the Feet' is a good idea, especially with the proviso -- per 1-L #2 -- that the Chin be permitted to Swivel right and left. [As Johnny Miller has observed, "The chin has a 'swing' of its own."] In any event, Geometric Golf demands a Centered Arc (1-L #1 and #2). At least as Centered as we humans are able to accomplish.

Now, assuming that stable Center is in place, any Hip Shift (right or left) will result in a Spine Tilt. As with the pendulum of a grandfather clock swinging from its hinge pin, that tilt will be either away from the target or towards it.

Clearly, through Impact, Hogan has both a Centered Head and a decided Hip Shift. Are you saying that he does not acquire a "rightwards spinal tilt by shifting the pelvis left"?
