Also had some problems w/ the short irons.
The EdZ "lift and roll"
I was lifting and rolling the club, laying it off at the top, straightening up out of my posture a bit, and would get my weight towards my toes. The more I was bent over the worse it got, so the short irons had the poorest results. I had to think more under and up instead of out and around...helped a lot. My backswing felt short and steep at first, but that "feel" changed quick and often, so verifying it via video was (still is) a must for me. Daryl's drill above would have helped me with this problem
Neil's post was an important topic for me, too.
