Yeah well the hands follow the arm I guess, haha! What most impact has on the move is the torso. So the no. 1 rule is that you need to look where you wanna go, and then the body follows your eyes... To initialize a turn to the right you might look back on your right shoulder... etc.

I might do a video about that, hehe :-)
