If he is referring to the Hogan type inward shaft lean, that is a peculiar way to phrase it. On the other hand, the lag pressure remains throughout the swing, indicating it is present even when the club ultimately passes the hands and ,therefore, through the various shaft flex points. And 7-11, states clubhead lag deals exclusively with sweet spot plane. So, lag pressure and shaft flex are different animals. To my untrained eye it is a little fuzzy. chipingguru View Public Profile Send a private message to chipingguru Find all posts by chipingguru
