I definately believe that normal females will always be needed in the breeding arena, even for morph breeders. People are not always going to want combos.. people will want, say, spiders and pastels. Which usually come from morph x normal breedings..
Normal males are great pet snakes IMO. I have a striped normal that, should he not prove out, I plan on keeping just because I am attached to him as a snake. Even if he does not produce anything genetic
