A great thing about the top Bar system, no heavy lifting. I can’t stress that enough. Also routine maintenence such as supering the langstroth’s to give more room for the bees is non existent. The entire hive comes in one box, their are enough bars to prevent overcrowding. if you are a wild child like me though, you could fashion a thing I like to call “super-ing bars” where as the middle bars of the hive have knotches cut out of them to allow the bees to travel up into an additional top bar hive, thus more sweet sweet honey. Also, got me with a nice paper wasp hive. I gotta figure out what to do with it now.
