I think that's the problem. The green change is so strong is makes unusual morphs very hard. Greg, Breeding with a het albino might get some of the crazy genes out. However, all the recessive mutations might not be a good combination. Just a small thought.
On a personal note, I'm a huge fan of snow cone. When I visited Rico late last year I was disappointed to see she wasn't there. It's a snake I would love to see in person.
