For most TBH's, it is difficult to transfer over a nuc. Your best bet is a swarm or a purchased package.
There are many who keep TBH. I have a few. It is just another form of beekeeping. Some folks have a problem no matter how you keep bees. (large cell foundation, plastic foundation, something other than a Warre, if you feed sugar, if you smoke, etc.) The list includes every management style, and every piece of equipment. So don't let the less than supportive comments impact your decision. Beekeeping is great no matter how you keep bees.
