The shoulder only stroke utilizes the turning of the shoulders on an incline plane. As with all strokes the hands educate the pivot so tracing a staight plane line, moving the putter head along a plane board (angle) or using a curved device (putting arc) will teach the shoulders to move on an incline plane. The right shoulder must move on plane to keep the putter head moving on plane during the shoulder only stroke.
VJ,
I have a Putting Arc (purchased about 3 months ago) and use a Shoulder Only stroke. I was surprised that you also mention using a plane board - are you referring to a 2x4, for example? If a 2x4 is used, then isn't that a "vertical arc" or a straight line? Are you suggesting that a plane board and the Putting Arc are equivalent training tools? (I don't expect so, otherwise why would you have invented the Putting Arc.) Please help.
I have seen some teachers (e.g., Pelz) recommend the straight-bask-straight-through stroke. Would you agree that this would require Vertical Hinging?
