[O.B.Left]

Yes the man had a certain way words didnt he!

I like the notion of the Left Palm laying flat to the Inclined Plane after what lynn calls Startup Swivel. It slides up and down the plane until the Release Point . In fact the non auto Release Trigger for the Wrist Throw is said to be turning of the Right (or Left Hand) off its flat to Plane Condition. (Big aside here.... it might seem like the club would move above plane but IMO it doesnt , cant as CF pulls it out, on line. Pulls #2 angle out . Im in the Lab here maybe)

So to answer your question in regard to what gets the left palm flat to plane on the backswing: It depends! Depends upon the nature of the shot , how much pivot is involved. If you zeroed the pivot say but got the left hand on plane (speaking theoretically here rather practically as thats a weird procedure ..... although I played with a 95 year old once who did this. He could stand up but he could walk) the arms would do far more than the pivot . Ill let you imagine the vice versa version.

This is where Independent Arm and Pivot Motion , Hands to PIvot (perhaps HKs second most misunderstood concept after the Angle of Approach PROCEDURE) comes into play. Homer called it Hands to Pivot but he didnt invent again. Its natural , what we do all day. In golf its been described in " Down to Scratch " 1933 , "Golf "by Robert G McDonald 1927 and the Wild Bill drill of course addresses the co-ordinated by but independent relationship of the arms and pivot. Simply put its golf motion in a manner similar to everyday motion or others sports motions as opposed to a contrived pivot centric manner of moving the hands. The body is multi levered by design , for a purpose , we are wired to co-ordinate the hands arms pivot when reaching , throwing etc . No thought required . No time required . For some reason in golf we cook up a very un natural body / arm motion. And steering. Our frustration with the game at first causes us to THINK and golf is not what it first appears to be. The angled nature of the club , the lie angle , with the little face makes it like very few other implements . We try to find a line , a straight line which is in end correct but we cover it when we should be tracing it. Hence Steering the clubhead straight back , straight through. Same sort of thing for the face. Add pivot to hands and you have the most popular procedure in golf . The hackers procedure. There being exceptions to most everything it can work for putting . Straight Back Straight Through , Shoulder Stroke . I dont like it but thats just me. Some do very well with it.
