Standing in the tornado is just part of it, and didn't really bother me, but it could for less experienced beeks. My biggest issue was trying to replace supers removed for inspections. With bees in the hive boiling out the top trying to leave the hive, and bees crawling up the front and over the lip looking for the entrance, it is impossible to put a super back on without crushing a bunch of bees. Even using the slide or twist into place method doesn't really work as the bees continue to head for the opening as it is reduced.
There were no benefits to me that outweighed these inspection difficulties.
