It depends! I prefer WWs and Gen 2 or 3 wolves usually. That's pretty much what you'll find in my den. Some people don't really care and just want pretty colors lol. As far as mixed breeding that also depends. There's some desire for pure Gen 2 and Gen 3 Brachs and Volmyrs but I've not really seen any demand for pure lines of other breeds. But there could be people out there that want that!
