scotts33 Since, I started the discussion, my definition is basic modern PGA type swings resist with lower body double plane swings. Basically what's taught by PGA instructors nowadays. That's how I look at it. I am sure others look at it differently.
Thanks for that, Scott. Do you know the history of when that became standard? I'm just curious. I know Johnny Miller had a big reverse C, but don't know if he used the X factor resistant stuff. Arnie and Jack were special. Ben Hogan seemed 'traditional' to me by your definition. Bobby Jones?
