Deeps may be cheaper, but not when you add in the neurosurgeon. I use mediums for supers, and with ten frame equipment, that is heavy enough. I will admit, however, that given my prowess last year with honey making, it would not have mattered. I did not have to lift any full supers - deep, medium, shallow or otherwise. Perhaps I can do better this year. My one remaining hive has pollen coming in like gangbusters.
