I was just about to point that one out. Really spectacular snakes though and I envy you for seeing them in person!
Personally I wouldn't count out recessive colour morphs to not explode since Albinos and Axanthics are everywhere despite that their prices have dropped a considerable amount since they first came into existence so you can assume that a lot of people think that they are genes that a very much worth producing. I really think that once Criders/Ultramels come down in price just a tad more, a lot of people would start grabbing them for their own projects.
As for Sunsets, those are definitely going to be the talk of the town in the years to come. I imagine some really crazy combos can come out of them.
