I'm going for the easiest route to solid golf. Tho my flexibility makes it no concern to me, would you say that many pro swings are along the lines of 10-7-C Master Yoda?
[Bold by Yoda.]
Many players set up with Low Hands -- lots of #3 Accumulator -- and 'hanging Arms' (Right Forearm not On Plane) and then use a Shoulder Turn Takeaway (which puts the Club too low). These players have little choice but to at least Single Shift (from Elbow Plane to Turned Shoulder Plane) and probably to Double Shift (return to the Elbow Plane during Impact). So, yes, you see a lot of that.
