I'd still like to hear how people load it . . . I think picking up the loading is huge . . . but to me it is more of a subtle deal.
Exclusive of float-loading, behave in a way from start down to follow through (and on to finish) in order to maintain and continue to load already established (for example - one can resist backstroke motion prior to start down) clubhead lag pressure (clubhead feel). Behavior includes the reaction of the body (reaction of the body can be practiced and trained - per 8-1).
As far as "quick" and not so quick start down, study and look at 2-C, the drawings of arc (swing procedure) and angle (hitting procedure) of approaches. With a quick start down (hurried) look how easy it would be to veer off plane for a hitter and his angle of approach (at top - its almost as if you are "on top" of this steep plane).
