I am into amarali boas, and I have 3 from Barry Miller and 1 from Constrictors NW. I am looking into getting another female around x-mas but I don't know if I should try to get a female from a different source to mix up the blood in my collection or get a female from Barry Miller that is a litter mate already to 2 of mine. I am really only going after the Joe Terry(silverback) bloodline if that matter any.
