What if it isnt just a Sameness deal? Im thinking Swingers benefit from the on plane right forearm too. Luke posted something on this today. If it was just dead weight Swingers could just use one arm, their left.
Bucket, I like your lever extension stuff but does it have to dispense with the Machine Concepts? Is there an advantage to the Bob?
Bulldog, I like your notes about the implications to the Pivot Center for those who dont preview impact in Fix.
Daryl, I'd suggest there is a reason Eldrick bobs and it has to do with how far he has to drop his right shoulder to get his Right Forearm on plane with a bent right elbow at Impact. Axis tilt alone isnt going to do it given where he starts. Im seeing on plane right forearms in baseball, tennis, hockey, its just a structural fact or law. I bet none of those guys know anything about it, but they do it.
