Of course you can have options .

I think it also depends what the student is actually doing. A student moving his head 12 inches back will require a slightly different message to a student that has a reverse pivot.

Per 1-L-2, the head is allowed to turn (but not sway or bob), but surely this rotation will change the way your eyes look at the ball. Doesn't this make the "eyes argument" obsolete, as I do not know of any great golfers who does not turn their head slightly on the backstroke? Unless, of course, you can tell the difference between a head turn and a head sway by using your eyes, which I certainly can't.

It's a shame Homer didn't add anything about the eyes, even in the 7th edition. Maybe he expected us to work it out.

Homer mentioned the eyes. And, I believe it was in the tapes from one of the Master's classes. It's a shame he didn't write about it and put it in the 7th.

You might not see it. But, let's not throw a "surely" out there just yet. You're a great ball striker, so I know you have the ability to perceive minute differences. If you say you don't see the difference, I have to believe you.

I find a very big visual difference in what the eyes perceive when the head is swaying versus the head turning. Most have the ability to move their eyes in the sockets...like this: If your eyes stayed fixed in the sockets, I could see that it would be hard to differentiate. I know your eyes do not.

I can focus my eyes on the tiny power light on my computer monitor and turn my head. As I turn my head, my eyes stay focused on the light. So, my eyes turn to the left as my head turns to the right.

When swaying, even the smallest amount, I notice the sway. There is a visual difference.

An optometrist will have to describe the way the eyes triangulate to see the differences. It's not my field. But when you sway to the right, the right eye has to be looking down the hypotenuse of a right triangle. And, your left eye would have to be looking down the shorter side. Your head would only have to move the distance from the center of your nose to the pupil of your left eye, for it to become a right triangle.

So, “obsolete” is a little harsh.
