I think that both can be done. The biggest deal about S&T or the M**** stuff, is about the Biological relationships when an athletic move is being done. The head must remain as still as possible.
That raises the question what type of movements must be done to do it.
I don’t debate on were or what really is the center of the swing. The reality is what is going to keep the head still (or as still as possible)
Another situation about the spine on this model is that your spine is not fixed or is it staying in the tilt as it would seem. You’re trying to change the relationships of the lumbar, thoracic and cervical spine through out the swing to keep the head there.
