[O.B.Left]

Golly I must admit I have a hard time visualizing all this. I wish each of you had a plane board to demo your concepts on. Then I could see where the club head, club shaft and hands were in each of your descriptions. I think it is difficult to tell where the camera is in the pics shown. I know that some think the camera must be placed on the plane of the hands and at hands height in order to properly determine swing plane. I always thought that physics would dictate that swinging in a circle(ellipse) the thing swung would try to remain on the same plane. So If you are are hitting a driver with the ball foward, close your stance so that your plane is a little to right and swing how does swinging left fit in? If your hands and clubhead stayed on plane they would go left anyway. Wouldn't more left be off plane and under? This is all giving me a headache although I must admit I am bookmarking it to my Best of Lynn Blake file.

I totally agree , no need for a headache you got it right.

For flatter Plane Angles there is more In and less Up in the Three Dimensional orbit (forwards, up and in post low point). So Elbow Plane does have more Left (In) to it than higher plane angles. But to do this and swing left in a non aligned to the base line of the Inclined Plane manner is to risk what Homer termed "Bending the Plane Line" as the clubhead orbit goes three dimensional . .. non planar, with all its loss in precision and power.

Plane shifting can and should have no effect on the Base Line , Plane Line. 1-L-18. In this way the clubhead orbit stays 2 dimensional and the plane is not "bent".

Heres a plane board , but one that shifts angles (double shift represented here) while maintaining its aligned to the plane line relationship.
