Hitting/Swinging?
 

This may not be relevant to the original question, but bear in mind that Mr. Miller is a Hitter (with his irons - and one of the best iron players ever). Seve may be Swinging, which would imply a different Hip Action.

where did you get that johnny miller hits his short irons looks like a swing to me

Mr. Miller
 

BantamBen,

I think this sequence shows Mr. Miller doing a couple things that Hitters are supposed to do - in particular, clearing his right hip out of the way (so his hands can go straight up, back, and in to the Top) and using Angled Hinging.

Those actions might become more obvious when compared to this sequence of Tom Weiskopf, whose hands go more around his hip on the way back and who has his right hand more on top of the club in photo #10 (indicating Horizontal Hinging).

I don't know whether it's possible to get an idea of how their Hip Action differs from the still photos, but if someone could make a "video" of the face on sequences it might be instructive.

Think of this move as if you were 'breaking a door down' with your left shoulder. You would brace back into the right leg (maintaining the angle) with a gentle slight slide, then turn as you 'stored up' your power to push off with the right leg.

A very rhythmic move that flows as one motion.

Great illustration on how the hips work Metallion. I always thought the hips turned in a barrel. Does this imply that the shoulders tilt as the hips slide?

One of the snares, Swaying refers to the head, not the hips, correct?

So as long as the head/feet tripod is fairly steady , the feet firmly planted on the ground, and the head ideally stationary, or its movement minimized but still centered between the feet, one can slide the hips all they want , even on the backswing?

Not sliding the hips in the takeaway has been a recipe for my head moving to the right and not returning them between my feet.

Another thing. Wobble in I-L, refers to the head and its associated tripd with the feet, and not the hips, correct?

Wobble refers to any part of the machine that is moving off plane, out of sequence, or with no benefit to the application of the line of compression (out of balance force).

Think of an unbalanced tire. It effects the entire driving experience.

A steady center is certainly a very critical part of eliminating wobble and of creating efficient force, no wasted motion. Many people have 'wobble' in their grips, which is an important area to look to. The Flying Wedges alignments are a key way to ensure your motion does not have wobble.
