If you have an unusual location, then for best demand for the offspring I think you'd be better off finding a mate that "matches". The rosies I've kept were first, Mexican rosy boas (I had one pair of them- the chocolate & cream) & then local high desert intergrades. For breeding purposes, they'll all breed, just less certainty the outcome appearance. When I lived in the high desert there was a fair amount of variation- some showed much more coastal influence, others more desert (straight & defined stripes), some had more orange-rust color, & some brownish stripes. If you just like rosy boas, as I do, I love them all. And my "intergrades" were very vigorous- strong feeders. Nothing like the one time I bred the obviously inbred* Mexican rosy boas (*the source had assured me they weren't siblings but I didn't believe that once I bred them- the offspring were wimpy & I ended up selling the adult pair as pets. I like snakes that are survivors- what nature intends.
