To my mind some of the confusion around this topic relates to the perception of what the "THE" plane really is. Some see it as a single non shifting plane, the shaft plane that the club travels only below the waist. Others see it as a shifting plane of glass.

See Mathews animation 1-L-18 which shows the club traveling along the plane as it shifts up and down all the while maintaining a straight base line.

Jeff your diagrams of Appleby might seem to suggest a curving path of the hands and a shaft non aligned to the plane at times. Leadbetter came to a similar conclusion I think. But what if App's plane line was drawn to show his shifts? The hands in 3-D space might still travel in a curve but the club might be seen to remain on the plane at all times with the butt pointing at the baseline. If he is on plane, that is.

I believe the club may cock along this (shifting) plane as well if you cock it correctly and at the right time. Golfers with an early right hand wrist cock for instance might be cocking off plane. I saw Tiger practicing this on Saturday at the Masters. Golfers employing extensor action and a shortening side of the triangle to cock the left wrist with the bending right elbow after swiveling onto the turned shoulder plane, will to my mind, be cocking on the shifting plane.

The relationship of the left wrist to the shifting plane is of interest to me. If the palm of the left wrist lays on the plane at top and the left arm is above plane the left wrist must be bent. Grip type may influence the degree of bend. Impact or follow through often sees a flat or arched left wrist.

All of which leads me wonder about this threads original topic, "the plane of the left wrist cock". If it isnt in line with the left arm but on plane, I wonder about the implications to the left wrist bend. With an apparent contradiction to my, no doubt limited, understanding of the Left Arm Flying Wedge and Rhythm.

Yoda? Are we correct in thinking a swinger should bend and flatten or even arch his left wrist? A use of horizontal wrist motion to align the club on plane? Or are we misunderstanding something?

It may be that words fail to properly describe the topic at hand. Mathew, have you had any success trying to render this? It would be an achievement of monumental proportion if you were successful. If you have tried Im sure you have insights of interest to the forum. Any super roughs, thumbnails?
