I love Axanthics and combos of them and I'm really looking forward to producing some combo stuff in the future.
Other morphs can lose there appeal over time by browning out as well. Doesn't mean I'll drop my Pastel projects though, just that I'm more carefull of pairings and what new animals I buy to add to my breeding stock. There are some nice adult axanthics out there and some not-so-nice ones. Same goes for almost every morph (exept pieds). Its all in selective breeding.
