I like the tought about standing leg sends the body--> body leads the moving leg along the path way where the weight is taking, detail technique described by key words.
Last night , my coach told me to hold RF ahead the LF in CBMP while my body weight travels onto left heel on 1 ( natural turn, waltz ). There is a delayed RF swing and very strong CBM, head is extremely left side. I am not sure whether it is better than the old one.
