I'm in a very cold climate. I run NO deeps at all. I cut all of the ones I had down to mediums and that's all I buy. In fact NOW I'm only buying eight frame mediums.
Well to be PERFECTLY honest I still have two deeps with bees still in them because I haven't gotten the bees to move out yet.
If you run no excluder (and I don't) then why do you care where the brood leaves off and the supers start? It's just a matter of enough stores for the number of bees for your climate and if it never really gets cold you can always feed if you run short.
