Back to the keeping the head still question.
1) Do you find it easier to keep a steady head with a narrower stance?
2) In order to keep the head centered between the feet on the backswing do you find that your right hip turns behind you a little and your left knee bends a little towards the ball? Then on the forward swing the opposite happens and the left hip turns behind you and the right knee bends toward the ball a bit?

Is this the Hula Hula action needed or do I have it wrong?

Steve,

I personally use a wider, not narrower, Stance. But there are no absolutes here: Just not so wide as to unduly restrict the Hip and Shoulder Turns or so narrow as to promote instability.

The Hula Hula Action refers to the ability to shift your Weight (Hip Slide from left to right and back again) while keeping your Head Stationary. This Motion -- followed by a Turn -- causes the Spine to Tilt in the opposite direction of the Slide (in both directions). Don't confuse proper Extensor Action at the Top (stretching out the Left Arm and the Left Shoulder Wobble) for a Spine tilting away from the target. Check out Jones and Hogan for the correct configuration and gain relief from this major misconception.
