I'm not necessarily against hybrid breeding..... I think that the superballs are a fantastic looking hybrid I just don't know if I agree with muddying up the gene pool like that. I just think there are too many variables when trying something like that.
If you look at Russo's superball page you see that there are varying degrees of hybridization (lol I guess that's what you'd call it). Some that look like they're mainly ball python, some mainly blood and some that are a really interesting mix of the two. I think that as long as they are represented in an accurate way and sold responsibly there should not be an issue with hybrid breeding. Just my opinion.
