Just in tonight, Daryl. For now, just know...

The perpendicular plane of the Left Wrist Cock Motion and the inclined plane of the Clubhead (Sweetspot) Line of Flight are two different things!

But doesn't the shoulder rotation mean that one creates the other?.If I take a dowel in my left hand and grip it halfway down ,take it to the top ,cock my wrist- I am on plane.If I then bend my wrist this does not move the dowel "off plane"-it just rotates.Thats why I stated that whilst the plane of the left wristcock is not the inclined plane ,the hands and the clubshaft are the plane but the left arm,depending on which point in the swing -(but Daryl did say at the top)-is not on plane.
