Hey Jack, We have several lady CMBA members that I know are running e medium
supers in lieu of 2 deeps with know problems.  Marcia M. gets loads of honey
with this set-up.  I've been running a deep with 2 medium supers on top,
started from nucs, and the 2nd year I move one of the supers to the bottom
followed by the deep and then the other medium.  I don't rotate my boxes in
the spring but I do move the frames of brood from the top super down to the
lower super.  By spring I find that the bees have pretty much disposed of any
honey in the deep box and it is easily accessable (after removing the top
super) so that I can get in to make nucs or whatever.  Honey production does
not seem to be affected.
