I have seen them. There is some info out there here is a link to a forum thread with a pic of a carpet ball crosshttp://www.constrictors.com/forums/s...-python-hybrid No I am not going to bash you, but I am not a fan of hybrids. They do however sell for remarkably high prices in my oppenion.. I saw a spider ball x carpet cross that bob Clark had a while back and he wanted close to 2k for it. I was amazed, I can see how someone would think it was cool, but I would never own one or breed for one as far as that goes. I can tell you there is a fairly low success rate on most hybrid projects.
