Ok Brownman, I'll bite. Are you meaning single wrist action for startup?
That's what Stricker uses, in my opinion. Hands remaining vertical to the ground during startup - could the hook be from single action backswing and then, instead to the gradual rolling of the clubface to followthrough for the hitter, you're simply over-rolling aka sequenial release (swinging?)

you don't mention what clubs you're doing it with, but are you taking proper impact fix for hitting?

Regarding the club face, hitting is the gradual and constant rolling of the face, while swinging is the uncocking of the left wrist THEN swivel to impact...
