I am a 12 with a very in-to-out move. I have no problem with distance, but my plane is very flat.

I tend to hit down very hard and deloft 2+ clubs. I have a low trajectory.

I suffer from an occasional hook with my long irons. My divots with mid irons point out 30 degrees, but the ball lands just over my shoulder at address. To hit a straight shot, I have to open the face way up.

I have lots of distance, but need some more accuracy.

Can I do something about my plane at address, so I don't have to worry about it while I swing? I have slightly more knee bend than average, but this is comfortable and i can do it the same way every time.

I have long arms (6'2" span, 5'10" height), so I look like an elephant at address. I have had a pro check the loft and lie of my 9 iron and he said it was fine. Meanwhile, I can hit my girlfriends long irons, which are a little shorter (mens reg shafts) quite well.

Any thought?
