The bent right wrist is FROZEN until at least follow through (both arms straight.) I have one of Mark Evershed's "Powerclicks" (a Tom Tomasello trained teacher, I believe) anyhoo...my right wrist flattens a smidge (a few degrees) just past my follow through, then bends reforming my original hand alignments in my finish. So start up swivel...CLICK....swiveling out of followthrough....CLICK....reforming my wedges to finish...CLICK. When I hit I get just two clicks, because I start at fix. Hitting is super efficient as you have discovered Brownman!
Check out (again as the case may be) Yoda's Dowels and Wedges video. He discusses the right wrist bend. Personally that is the best couple minutes of golfing instruction EVER. Flying Wedges, Turned Shoulder Plane, Straightline Delivery Path...it is all there in just a few minutes with the effervescent Green Sage. My favorite line "You are not going to see that in Golf Digest next month!" True that!
Can anyone out there swing/hit a full bore drive maintaining a bent right wrist throughout? Any world class players who can?
