The club will hinge by itself if you let it.

BerntR,

I know you 'get' it, and I appreciate this and all your many valuable contributions to our site.

Further, I know I'm being 'picky' here.

But . . .

It is the ENTIRE Left Arm Flying Wedge -- the club AND left arm -- that 'hinges' from the left shoulder.

Not just the club.

Then again, that's the whole point.

We need to stop thinking of the 'club' and start thinking of the Machine and its controlling Structure. Through Impact, the Flat Left Wrist (executing one of its three Basic Feels) unites the Left Arm and Club. In so doing, it controls the Clubface (and its alignment) and the Clubshaft (and its in-line Rhythm with the left arm). And, also, the Clubhead and its in-line 'travel' (through Impact to the end of the Follow-Through / Both Arms Straight position).

Clubhead control -- Force (physics).

Clubface and Clubshaft control -- Alignments (geometry).

Force -- aligned -- becomes efficient.

And that's a good thing.
