YodasLuke,
Thank you so much for posting. I would have responded sooner but my cable modem has been toast. It only takes close to a week to get a cable tech to come out to the house. Gotta love the rural life. Nothing happens quickly.
Anyway, those quotes from Homer confim my findings. In fiddling with the procedure I found exactly what he's saying to be true. I too was concerned because I found the travel of the club with the clubhead covering a straight line to be steep as can be. "Actually, it's a vertical plane for the clubhead" (slight pause) "slightly inclined." Feels odd at first. I kept working it though because I was trusting 2-J-3-B. I knew a circle on a inclined plane can appear to be a straight line from viewing circles at different angles. If you look directly down on a plate or hula-hoop, etc. you see a straight line. That object can be slightly tilted and still visually appear straight. By using Angle of Approach I find a Hitter is guaranteed inside-out impact.
I like the straight line feel of the clubhead because it feels right with the straight line thrust of the right arm.
These ring particuarly true for me:
"You're not concerned with the clubshaft."
"The clubshaft seems to be immaterial."
"It represents a clubhead plane rather than a clubshaft plane."
"Line momentum of the clubhead."
I'm still not sure why 10-5-0 reads the way it does about synchronizing by laying the shaft on the line. Especially when he says this in a Master's class, "It's not a true on plane motion." I'm still thinking on that one.
So, from the posts and my own findings it seems the thing to do is: setup with proper alignments at Impact Fix, locate the straight line Angle of Approach through impact and low points, let the Clubhead cover the delivery line and let 'er rip.
I like it.
