To quote bts from this thread

For your regular (Swinging) swing, the Right side is supposed not to disrupt , but reinforce , that Motion and Action.

Like you OB, my golf season is over until the spring but I think extensor action and using my right forearm to guide my left arm should be my winter project.

Back on topic, although I seem to be impervious to extensor action drills... I'd love to have some stuff to work on over the winter that can help move that left arm swing toward right forearm, shoulder control.

I certainly don't have any trouble with right forearm control while hitting, it's just that swinging is a flail, and intimately tied to the left side/pivot.
