If I were to start over, I would go with all mediums. I currently have deeps for brood and shallows for honey due to getting GREAT deals on woodenware from dead beekeepers.... Okay, from their families... Pam's hive is all mediums, as is her granddaughter's, and they'll continue with that as they expand their hives, just so they only has one size to deal with. (Weight is not a concern, as I do the lifting....LOL)
