There HAS TO be axis tilt at setup, HAS TO be because your right hand is lower on the club.
The only way NOT TO is if you setup with open shoulders.
One of the reasons a lot of folks could benefit from the way Mike Austin/Dunaway approach the setup process - setting the left arm and club inline first (left flying wedge) and then kicking in the right knee slightly to lower the right shoulder and add the right hand grip.
An excellent way for hitters to setup to the ball (see Ted for the perfect example of this approach).
Very useful for encouraging a hitter's crossline hip motion, and tends to error towards closed shoulders rather than open. Can be 'overdone' however (too much tilt).
