I like your post and know well Geoff Mangum's research on putting. Putting has three imperatives, a straight plane line (whether vertical or inclined), lag pressure (for distance control), and a shaft which is vertical to the ground (or slightly leaned forward) at low point. These are the mechanical imperatives to putting.

Tony Sills introduced me to visual training some three years ago. The shift I see coming in putting will be to the eyes and the alignment of the putterface. There is a lot of research (Geoff has a good bit on his site) pointing to the importance of understanding the way in which the eyes work to help or hinder good alignment of the putter. But, this work belongs in the in Zone 1 for the golfing machine, not in Zone 2 or 3.

Again, we retrace our steps and we find that unless the pivot does its job, the arms and the hands will constantly compensate for the pivot. However, the better the mechanics, the better the compensation. In other words, the more educated the hands, the better off we are with the flat stick in our hands. Uneducated hands can be the whole problem and never even be suspected.

So............stay pigeon holed while while we research.
