While all of the modern hives are made to be applied to each other maintaining bee space, and setting one on the other, in my experience I find it quite a bit easier in one respect to use only one size of super for everything. unless your in a area that doesn't have a very strong nectar flow, or your trying to make comb honey, seems advantagous to one one type of super, either medium or deep/ hive bodies. For some I understand it's the wieght, but seems to me that the advantage of not have various sized super equipment in the honey house makes sense no worries about mixing or matching. Just my perhaps convoluted thinking :? .
