I personally love hybrids, but even people who don't mind hybrids will say that carpalls really arn't that hot of a snake really. While things like carpondros are just stunning. If you want to do hybrids you might want to pick a different pairing. I would see selling carpalls being very difficult just because very few people like them. Carpet python with a ball python head, maybe if some morphs got mixed into it, might be interesting, jag x pastel or something like that.
just some things to think about
