If your feet and legs are good to the top, no sway, braced, solid right leg, then the downswing flows back to the center, see Brian's frisbee throw pics. Brian, I think, feels the left foot bump towards the target and quickly braces into a strong solid post. And duh, the arms aren't looking for a reason to move. They are dropping to the center, low right shoulder, power package intact, hands moving to the left as clubface removes ball from the earth.
If the legs are good to the top, then I think the mid section starts the swing, ie/ belly, hips, and depending if hit or swing, either knee and thigh. Get your penis to the ball then toward the target with hands to the left ear.
