Flying wedges and pulls/pull hooks

[KAOS]

Hi, great forum, guys.

I'm just becoming acquainted with TGM, and rather than immersing myself, I'm tiptoeing into the Book of Homer and Lynn's forum. I've concentrated on the 3 imperatives & essentials from the Book of Homer with emphasis on the moment of truth and making sure that everything's in line. Before I even heard of TGM, essentials 2 and 3 and imperative 3 have been the keys to my game. A little bit of clubhead speed has also helped.

I can say that just by focusing on maintaining the flying wedges (a la the bent right wrist) I drove the ball beautifully this weekend. Missed one drive with the driver, and even that was very playable. The most remarkable improvement was shot trajectory, and I was able to take advantage of tail winds and cheat head winds as necessary.
So far so good...

But my iron play was deplorable. Despite hitting 10 fairways today, I managed a paltry 8 GIR. Yesterday it was 12 and 10. The mid and long irons were usually WAY left of target, either straight to way left or just left,left,left. Short irons were slightly better, but contact was on the thin side with the occasional push. Trajectory ranged from normal to a bit on the low side. Distance was normal.

It "felt" like I was spinning my shoulders out, and my upper body was very open in relation to the target at impact. Weird thing is, that by concentrating on maintaining the flat left/bent right wrists at impact, it got even worse.

I'm a swinger with a strong left/neutral right grip. Normal ball flight is a slight fade or slight draw (maybe a 60/40 split).

Any help out there in terms of thoughts or drills? Thanks.
