FLW throughout the entire swing?
 

Does it say anywhere in the book how long one should maintain a FLW? My instructor wants me to hold it almost to the finish, which is quite hard to do. It helps me strike the ball very very solidly, but it's going to take a butt load of practice to ingrain this into my swing. I was looking at Tour swings on youtube and I couldn't find anyone that didn't break a FLW during the swivel? Should I keep on practicing this or is it not quite necessary to build a solid swing?

Thanks!

Terminology
 

Sorry if I'm botching the terminology I'm still pretty new to TGM...

See 6-B-3-0-1 THE FLYING WEDGES and reference Yoda's comment about the flat left wrist in one of the Gallery sessions with John Riegger. Maybe someone will comment on the exchange with John.

DRW

Yep! The last sentence:

Then, ideally, the Left Wrist is always Flat and the Right Wrist is always Level.

I guess it's time to get practicing...

Flw
 

As I understand it:
The flw is the angle in the primary lever at the left wrist. notice I do not say cocked because the wedge exists until #3 accumulator reaches zero (uncocked). that will not happen until both arms straight at followthrough. but. the wedge is flat to the left wrist at impact(level also-don't confuse). How it gets there is a function of hinge action . Cocked at release-level at impact/or low point-uncocked at follow through. always flat

I think your instructor is exactly right.
