Of the current world class players that I can think of...Scott Hoch is the STEEPEST and Dana Quigley(Alan Doyle close) is the FLATTEST on their backswing planes. The rest are somewhere in the middle, although FLATISH seems to be making a comeback in popularity.
How about a discussion on what makes these two extremes work...GRIP, SHOULDER TURN, HIP TURN, PLANE SHIFTS, DELIVERY LINES, etc. Maybe if the two extremes can be understood, then the middle(with hopefully less compensations) can be better understood.
IMO ,Hitters would benefit from a steeper plane,Swingers more from a flat-ish one.
Lots of other factors involved of course ,but Tour Pros can take it back how the hell they want -and still get to impact in impressive alignments
I really do not think there is a "best"way. How many variations are there?
Then you can X it up.
Good point though- too late for me on a Friday
