I can't resist asking you guys about this one:

Maybe you've seen the Gold Digest's Swing sequences of Sergio and Ernie.

Sergio Quicktime
Ernie Quicktime

When you look a Sergio in slomo, you can see the shaft loading on the downstroke and staying bent until it is waist high.
You can also see how he "Float Loads" with his left wrist cock increasing on transition to downswing (exactly like GolfBulldog said).

But when you look at Ernie, you never ever see a bend in is shaft during the whole swing...and you won't see him float-loading because is left wrist cocking angle stays constant during the transition.

I can't think we could say that Ernie is not loading the clubshaft? So where is the trick?
Is he using xxx-stiff shaft that never bend or what?

One more question with Sergio: I said that his shaft stays bent until it reaches waist high. At this point the shaft seems to loose its bent and even "bounces back".
Does it mean that Sergio has lost his LAG pressure too early?

The key is that at impact, they both provide 'support' - lag pressure. Ernie is using more of a sweep release vs. the snap of Sergio, a more consistent pattern on Ernies part IMO, easier to control distance in my experience. Ernie is 'lengthening the shaft' - sending force straight down the shaft towards both arms straight.

Re: the lag pressure/shaft motion - yes, sergio has lost his lag pressure or is in the process of doing so, because his shaft is probably not quite the right fit, and/or his aiming point or transition ratio may be off. The clubhead is seeking out its 'in line' relationship to the forces acting on it, which is not, as in Ernies case, straight down the shaft.
