Personally, the only reason snows dont just blow me away is the fact that we have so many other, easier to produce combos that create all white snakes. Cleaner all white snakes, imo.
The lavender snows are completely different though, and completely stunning. I'd love to see if a Candy Snow would have stronger purples or not.
But to stay on track with this thread, a quadruple het to quadruple het breeding would likely (unless you kill the odds) take decades to come to fruition. I know one of the forum members here just recently on a whim paired a double recessive to another double recessive (Albino Clown to Ghost Pied if I remember correctly) and outlined the odds of producing a quad animal in his own thread.
EDIT: Of producing a quad animal from the quad het offspring I mean. All babies from the original breeding would appear as the wild type.
