i sure wouldn't. why change what is working. there is debate about yearly requeening and i think most people have come to believe that it is not necessary. every other, maybe and probably more important for a commercial beekeeper, than a hobbyist. for us, we can go according to how our hive looks and what our finances allow. i'd guess that my hive will requeen before i get around to it. at least i hope so! it will save me the money :-)
