i don't reverse. i keep bees in double deeps. the bees are smarter than we are and know what to do. same concept applies when hiving a package or a nuc. hive them in a deep or two mediums, and when they need the extra space, place it below them, not above them. this goes against everything we have read or for some, what we have been traditionally taught to do. not sure how to explain this or why it works, but it does. the bees move down. winter; the queen and bees move up during winter months. when pollen and nectar become available, the bees start filling the top box/ boxes and 'move' the queen down. they move down on their own. reversing can sometimes separate the brood, and most often times does because the bees are in two boxes irregardless of the configuration.
like ray, and many other northern keeps, i have found myself short on getting queens when i want them. i keep an eye on what's going on. best thing to do is utilize queen cells to make up nucs/divides/splits or light divides to my best colonies to avert swarming and/or sometimes also added supers or supers of foundation to keep them busy and keep them from swarming. no excluder with foundation, and no excluder with drawn foundation until i see these being worked and filled, and before the queen gets really busy and laying up in them.
bees will swarm. it's their nature.
ray, i have kept 3 deep systems, a lot of hard work.
