[Yoda]

I know because I have done it (STEERING) for many years. I read where Homer said that if you could learn to play with a FLW, you would break 80 tomorrow, so I started holding my wrist rigid through impact and it killed my swing. What Homer did not say, but is understood, is that you must learn to play with a FLW while sustaining LAG.

The Flat Left Wrist is the desired mid-condition of the Wrist's Horizontal Motion ( Flat, Bent and Arched). Steering is, primarily, holding the Left Wrist in the Turned condition of its Rotational Motion (Vertical, Turned and Rolled) thereby inhibiting its proper Roll (to the Left) 'through the Ball'.

When you attempted to impose the Flat Condition in your Horizontal Motion -- remember, Homer also always said, "Willpower isn't enough" -- you unconsiously inhibited the correct Rotational Motion (which, almost certainly, was the true problem to begin with).

You are now using a personal Zone #2 (Club Control) 'Feel' key -- Clubhead Lag Pressure via a "completely relaxed" Wrists -- and that is allowing the correct Rotational Motion to occur. Be sure you understand the correct Mechanics (Wrist Action / 7-18 and Hinge Action / 7-10 and their Variations in Chapter 10) and how your current Feel enables you to produce them. This knowledge will enable you to maintain a Firm Grip (1-L #3), yet still achieve flexible Wrist Action (4-0).

Congratulations, elliskit!

You have met the Golfer's Public Enemy #1 -- the first Snare . . . Steering -- and emerged victorious!
