It must be that time again to start pondering whether Top Bee Space really is better than Bottom Bee Space. Currently all my stuff is Bottom Bee Space and having gone over a few hives this year using Top Bee Space instead I do quite like the lack of squishing that Top Bee Space seems to encourage over Bottom.

As I'm now on 14x12, having to worry about mixing brood boxes isn't an issue, but I do have a number of supers that would be a pain in the backside to convert.

When it comes to supers though I've come across two schools of thought:

"Thou shalt not mix top and Bottom bee space boxes or the world shalt end, thy bees wilt fly away and all thy honey shalt be Ivy".

And

"Just chuck em on, the bees don't seem to mind"

I can't remember what the third opinion was, but I asked two beekeepers so there must be one somewhere.
