Check out Jody's swing sequence- as with any other professional swing sequence.

The on-plane motion of the clubshaft directed by the lag really controls what motions will be made- the uncocking flat left wrist and any roll are really subservient to the on-plane motion. I could go into further detail regarding the flat uncocking left wrist, but I think it's pretty obvious if we start looking at swing sequences that the left arm flying wedge is never on the swing plane. However, if you've thought before that the left wrist would need to stay flat and on-plane for any uncocking to create an on-plane motion of the clubshaft then your're brain's going to scramble for a while- dealing with a different concept.

The easiest solution for a contrary opinion would be to put up or point out swing sequences where the left arm flying wedge is on-plane as you described. After all, if the left arm flying wedge is on-plane then the left shoulder would be on-plane. A

I had the sime thoughts Mike O,

Having been thinking a bit further, I think this can be refined a little bit. Assume the following premises:

1) the leftt wrist is flat from impact fix to impact
2) the club (not only the clubhead) is on plane from impact fix to impact
2) the left arm is steeper than the plan at address and impact. 10-6-B#1
3) the left arm is flatter than the plane at top of back swing. 10-6-B#2

As we move away from address, the leftt arm goes from a steeper to a flatter position compared to the swing plane. So somewhere in the middle, the left arm must at least be parallell to the plane (as seen down the line). Since the club is on plane throughout, left arm will not only be parallell, but also on plane. But this will only be at a point in the swing.

Where's the point? It's the point where the left arm is parallell to the ground. From a "pure geometry" approach, it cannot be otherwice. Or?

Edit: The text was a bit lefty and righty oriented - now it's written for a righty swing.
