Well in so many words as Yoda has put it, I developed a very vicious underplane backswing under the guise of "you dont hit the ball on your backswing".

Well, you also don't hit the ball on your follow through, so does that mean you do it any which way you want?

No.

And so it is with the backswing...it is a portent of things to come.

Watch this space for more.

Homer Kelley disagreed, in fact Yoda said in 2006,

Homer Kelley told me:

"You can 'clown' the Backstroke," i.e., take it back however you want (and from whatever position you want), but at the end of the day, per 1-L #20:

"For any given Line of Compression, every Machine must produce identical Impact Alignments."

I think Homer was much less concerned with the backswing than people here today, and much more concerned with getting to the Top/End with enough physics potential to deliver those Impact Alignments with as much clubhead speed as possible.
