Let's see if we can agree on certain fundamentals.

I believe that one needs to keep the power package assembly intact in the early downswing, which means that one must maintain the right flying wedge intact, while the lower body undergoes a pelvis shift rotation movement - irrespective of the downswing trigger.

Do you agree?

Here is posed photo of Hogan's swing demonstrating what I mean.



The yellow colored area represents the power package assembly and I think that it should be intact at this point in the downswing - intact despite the fact that the hips have rotated about 45 degrees to a hip squaring position, and despite the fact that the entire pelvis has shifted a little left-laterally as one puts weight on the left foot.

Now, has does a golfer get to this position? Ben Hogan states that he thinks of starting the downswing with a lower body move - a pelvis shift-rotation move (hip squaring action) that pulls the power package assembly downwards . I used to start my downswing this way, but it was problematic for me because I tended to suffer from one-or more of these problems - i) too much left-lateral hip slide; ii) a tendency to move my hips too fast and out-of-synch with my upper torso, iii) a tendency to spin my pelvis and roundhouse my upper body. I now initiate my downswing with a right shoulder throw action downplane - and this works better for me because the right shoulder throw downplane causes my pelvis to move the correct amount as a result of a transmitted force going down the spine (right shoulder moves downplane => causes the spine to develop secondary axis tilt and simultaneously produces a transmitted force that passes down the rightwards tilted spine to the pelvis => pelvis shift-rotates to a hip squaring orientation). In other words, I still end up looking like Hogan at this point in the downswing - with a squared pelvis and the power package intact and the right elbow approximated to the right hip. My power package remains intact because during the right shoulder throw action, I also isometrically contract my right arm/forearm muscles in order to maintain the right arm flying wedge angles intact.

Now, if a golfer states that he trigger-starts the downswing with a right forearm throw, I can imagine that golfer end-up looking like Hogan if the right forearm throw is i) a throw of the entire power package assembly (as an intact unit) down towards the right hip area and ii) the right forearm is in a state of isometric contraction (and not isotonic contraction, which would straighten the right elbow and prematurely release power accumulator #1). Is my description of the right forearm throw action (that initiates the downswing) representative of Tom Tomasello's approach, or is it totally different?

Jeff . . . not to be nitpicky (which I reckon means I'm gonna be nitpicky) . . . but the shoulders are PART OF THE POWER PACKAGE . . . Your pattern is valid BUT you are not benefiting from the entire radius via Swinging from the Feet if you aren't starting the swing from the ground up. The radius ends at the first nonlagging component closest to the ground.
