What wolves are worth more and would make profit off of studdding?

Are you looking to buy a wolf to make your breeding male? If yes, this is the wrong topic; you should look in Wanted: Wolves.

Or do you want to know what wolves are generally desirable? At the moment I would say any Tier II base, RMA-exclusive markings, combo markings and Merle (losing value maybe though?). Known mutation carriers as well; high stats are also a plus.
