As for the breeding, it's one of those things that theres so many people breeding without knowledge of what they're doing (like mixing strains of albino) with "mutts" going around that it hampers some larger operations. It's not like ball pythons, where you can throw two together and make something, some times you end up (in Leo's) with normal double hets that won't produce something containing both genes (specifically the albinos again haha).
I'm aware of the different strains of albinos not being allelic and am familiar with a majority of the different morps found in leopard geckos. What made me ask about the mack snow comment is that by breeding a mack super snow to a mack super snow you will only produce more mack super snows, not some sort of mack super super snow, and if the parents were healthy then I see no reason why their progeny wouldn't be as well. The one leo egg that I incubated from a mack snow het tremp X patternless het tremper developed fully and thenn died in the egg before hatching. Maybe it was a result of what you mentioned?
