One Plane Swing with Mid-Short Irons

[robf]

I swing using the one plane approach with my driver and long irons I found this approach to be very successful really good distance and accuracy. Should I use the same approach with my mid irons and short irons (wedges)? I was always told to hit down on the ball. It seem to me that a flatter swing would be more difficult with mid-short irons. Has any of you guys had experience with the one plane swing and short irons?

I really would like to hear your thought and successes or failures.

Thanks,
