I agree with John. Compared to other "white snakes", snow ball pythons are very expensive. I see female snows for sale at some trade shows but I seldom see male snows. They are still rare. This keeps the price high. People producing snows are keeping their males but have been letting go of females. They are rare because a lot of breeders trying to produce them are still at the double het x double het phase so they are playing the 1:16 game. Unless you are a large breeder you will be hard pressed to give up one of your females albinos/axanthics to a 1 in 16 shot when there are so many other things that are more sure.
Also consider the value of the ingredients. At this particular point in time, people who have adult albinos and adult axanthics are more likely to do something else with them. There is a lot of effort being made today to produce visual co-dom or dominant animals that are het albino and het axanthic. Axanthic Black Pastels and Albino Pinstripes (for example) are more interesting and that's where the effort is right now.
Also, where are you going to go with a snow? So many of the current projects have opportunity beyond them. For example, Spinner Blasts are a big desired result for a lot of breeders. But look where you can go beyond that: Axanthic Spinner Blast, Super Spinner Blast, Spider Spinner Blast, Lesser Blast, Killer Lesser Blast, ...and on and on and on. As I always say: it is ENDLESS. But the Snow Ball Python seems to be an end. Unless one of these other genes added into the snow combo causes something crazy to happen it won't matter. Will a Snow Spider look really any different than a regular snow? Probably not. So why bother? That seems to be the attitude.
Sadly, this is a disease. Despite considering them a reasonably dead-end project, I still want them in my collection and I will still produce them. I can't help it. Methadone doesn't work for my ball python addiction.
