I only have the outside of my left foot on for that move and my right foot just flagging out in the roof to the right, it is really body tensiony. At your size TT you want to come to the first crimp (the one that Dal has her right hand on) with your left hand, get a right foot footlock in the juggy slot, match a sloper just to the right of your crimp and then roll through to the little pocket with your right hand.
