Ha, OK maybe I shortened and oversimplified my sentiment... In working with my DD who is a serial bat dragger, her over active and overly strong top hand (only at the INITIATION of the swing) leads to casting and bat drag for her. I would argue that if you had dynamometer (pull scale) attached to the wall, at the INITIATION of the swing (when your hands are near your ear or moving slightly back during load) I think you would be able to pull harder with your bottom hand than you could push with your top hand. Once the movement is initiated, I believe that the comment I made referencing the bottom had providing a stable platform was to infer that it delivers the power. To me a swing is PULL/TTB dominated by the top hand transitioning to the bottom hand delivering power through the hips at contact. Probably still too oversimplified, who knows. At least it makes sense to me....
