In my lab time I have noticed that there is a link between a centered/stationary head and extensor action. If the head sways in the slightest the checkrein action of the left arm is impeded. Is it kind of like a dog owner yelling at his dog to stop running away by running after the dog, as opposed to simply stopping and allowing the leash to do its thing! So the benefits of extensor action are diminished by any lateral movement of the head?
I understand how the left arm checks the right elbow and causes it to bend in a precise manner. This bending right elbow then cocks the right left wrist or permits CF to do it in the case of swinging. What factors determine the degree of left wrist cock? How much left wrist cock is needed in order for it to be sufficiently loaded? My left wrist does not cock a great deal. I look a lot like a drive loader with the shaft almost point skyward at Top. Is it an issue of flexibility? How do I achieve more left wrist cock without getting the right wrist involved? Is it a function of more right elbow bend, or is it simply the weight of the club loading against #3PP?
