When you say "on plane" am I right in thinking you mean the path of the hands or specifically the #1pp vis a vis the Hand Path you delineated previously from Top to Impact?

Do you prefer that analytically to the Shaft/ Sweet Spot Plane? Or do you consider them both?

Interesting, thanks

I personally do, yes. That said, you of course have to see what the shaft is doing, as well as sweet spot motion/rotation. Very few can have a good hand path without a good shaft/sweetspot plane and get away with it, and basically nobody can get away with it on the downswing.

Ray Floyd comes to mind re: backswing.

All of that said, a good argument can be made that if the camera is correct, all that matters is the sweetspot in an uncompensated motion.

Perhaps Ted and Jeff will chime in as well, as I know they'd both have good insights into their preferences.
