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?
