It doesn't really bother me... but you won't catch me doing it. I'd much rather have a clutch of carpets and a clutch of chondros. But hey, whatever floats your boat. Listening to Eugene Bassette talk about them on reptile radio might provide some better information, since he produces a lot of these. He refers to them as Cheviridis. A combination of M. S. Cheynei and M. Viridis. I remember him talking about knowing the genetics of what kind of chondro and carpet you are using, you can't just use any two specimens and produce viable offspring.
