In my opinion, it is counterintuitive to state that there is a sensory advantage to using the head pivot center, and yet still you (and Mr. Kelley) allow the head (and eyes) to rotate.

Well, Mike Finney, my sense of sight and balance, not to mention my hearing, smell and taste -- are all located in my Head. And 'touch' also filters through there on its way to recognition by me. To my mind, that's a pretty good reason to view the Head as Command Central for the senses and as a pretty important resource when striking a Golf Ball.

To tell you the truth, it's a whole lot easier for me to sense my Head than my 'Point-Between-the-Shoulders.' But maybe that's just me.
