EDZ, (And anyone else)
Since I haven't followed this thread throughout- I'd like someone to verify that one of the primary debates here is whether the head should stay still or the spine stay still and the head turns somewhat around the spine.

If that is the case then we would have:
1) The head does not turn or rotate at all- and the head stays still- and the spine stays still
2) The head rotates on the backswing and the head stays still - so that the base of the neck spine (Cervical) in that scenario has moved towards the target.
3) The head rotates on the backswing and the Cervical spine stays still so the head rotates around to the right on the backswing.
4) The head is pre-rotated- so that again the cervical spine and the head stay still.

There may be more options as I didn't put a lot of thought into this- but maybe others could add to it.

So both views have a stationary center at the top of the tripod- correct? , One has a stationary head with it and one has a rotating head with it.

Here's another question for Birdie Man or others- if you could pre-rotate your head to your desired top of the backswing location before you take the club away, then this would give you a still head and a stationary Cervical Spine- what would be the advantage to letting it move versus pre-setting it?

Those that favor head still- would within that context also be having a stationary cervical spine- correct? So the only difference is one is letting the head rotate and one is not letting the head rotate- and a pre-rotation would unify both camps-correct?

Finally, is there or has there been a perception that a centered spine would have a body "shape" that would show the back leaning away from the target at the top? Why would that be if the only difference is the amount of head rotation?

To clarify and summarize- via at least one previous post on this thread- you'll realize that I'm somewhat neutral on this "debate"- so the only agenda I have is learning more about the golf swing. And again, although I think I know the answers to my questions- I would just like Birdie Man or others who have been involved in this thread to confirm if I understand the issues or if I need some help in understanding them. I know I've got quite a few questions here and some of them repeat but would appreciate the appropriate feedback to confirm where I am on this.
Thanks,

My main point regarding using a swivel of the chin was to highlight the key reason that most people move their head. This simple address move has a number of very positive benefits to the motion, the most important of which is that it makes it significantly easier to maintain a dead still center. Additionally, it is very useful in preventing the right shoulder from going 'out' during the startdown - a very good way to help prevent roundhousing.
