My 2c

I think they have to slide, just a little, before they rotate.

Personally I feel like I drive my legs (knees specifically) to start the DS which shifts my hips laterally, posts up the left leg which the hip then rotates around. All the time the arms are being pulled down

Have a look at this great video clip about 40 seconds in where they do the front on views and watch the hips. They do move laterally until the left leg firms then they rotate around it. Adams left leg almost pops at the end he's driving so hard with his lower body

As for stopping, im not sure they do. I think its one whole motion. A powerful leg drive forward would he hard to stop. As soon as that leg drives has got me on my left side I rotate my upper body hard left. Of course the 2 motions happen so quickly - bang bang.. but I stuggle when I dont get that lower body left because then I rotate around my right leg and hit pulls/hooks all day long

so ... what's occuring mate?
