Hi,
        In my estimation all the ventilation arguments go out the window
when I look down on my top bars and see most of the space clogged with
burr comb. I have torn out all my frame spacers and like it better this
way. All (most) of my equipment is 6 5/8" with 9 frames (mostly) in the
honey supers. eyeball spacing. I prefer the flexibility of frame and
super shuffling. A perfectly great way to cycle out bad brood comb with
honey in it, delegate it to the honey super for a nice frame. The bad one
gets ditched after extracting. Perhaps you prefer to lug around a special
super(s) with frames to swap with? Tight frame problems are realy not an
issue if you remove the outer one before manipulating others.
