There is no question that the Pivot plays a vital role in the Lag Loading during the Start Down. Indeed, the Pivot accomplishes that Loading with no independent motion of the Arms and Hands (6-K-0). It is this sequencing that induces the Pull sensation of Drag Loading. Per 10-19-C (capitalization by Homer Kelley):

"Drag Loading is...an out-and-out PULL, striving to accelerate the Clubshaft lengthwise..."

Correct me if I'm wrong but I always thought that TGM advocated a Hand Controlled Pivot. Starting the downswing with the Pivot per 6-K-0 tends to throw the shoulders at the ball, and that 6-L-0 was far better as the shoulders are undisturbed by this initial move from the End. Drag Loading can still be accomplished with solely the hands and arms, and once complete, the Pivot "kicks in" to maintain balance through the remainder of the swing. That's the way I've been swinging -- and with good results may I add.
