Superball = Borneo short-tail Python x Ball python.....Not Blood python x Ball Python......
I would worry about any issues that involve hybrids...genetics, ethics, and how other people think of hybridizing reptiles. Personally, I don't see the point. It muddies the waters and has some people asking questions like "what kinda hybrid is that" when they see a new cool 100% ball python morph. Eventually you end up with a bunched of mixed species animals out there and noone knows for sure if the animals are pure. It has happened with lots of other reptile species and always complicates things.
I think the market for hybrids has to be pretty low, but who knows. Why would you want a hybrid ball python when there are so many cool morphs that are 100% ball python?
