Beeninja, I am not from your area, and I wan't get into the pros and cons of a newbee using a TBH. But are you buying ar building the hive? There are several different ways to build and have a SBB. Some just have a SBB, some have a SBB with a small space and then a board that either slides out or drops down. On mine there is a little distance between SBB and the bottom of the hive body. I made a tray to put apple cider vinager and oil for the mites and SHBs to fall into. You do have to empty it regularly. But any with something to enclose the bottom shouldn't make it alot more airy in the winter.
