[O.B.Left]

I wanna go back to what the centre of the motion is re the wedges.

Wouldnt the wedges attach to the primary lever? Which is centred at the left shoulder. So you spin your pivot in startdown and then throw out your primary lever and roll the wedges about the left shoulder.

Or is it the LCOG? (Bear need not answer he disagrees we know) I dont see the wedges as rotating about the spine.

Thats how I feel it, see it anyways. Sorta like a top spin backhand in tennis . Talking flail action here. Wedges roll together.
