This will sooo easily turn into another pro/con hybrid war. I agree, it's not the best idea to cross species and subspecies, but it's not that big an issue. These are pets and nobody intends to release them, or at least I hope that's the case.
But under my circumstances I could even call it a non-issue. Both of mine are from stores and both were imported. Basically, it's impossible to trace their lineage and for all I know, they are both "mongrels". They might look like a certain species or subspecies, but I'd be taking a risk even calling them T. sirtalis.
I don't disagree with GarterGuy's "Just because you can, doesn't mean you should.", but then again, just because somebody else wouldn't, doesn't mean you shouldn't. It's something everybody need to decide for themselves. I'd prefer pure snakes, but you don't always have a choice. That's unless one of you down there on the continent is prepared to ship pure T. marcianus or T. atratus to Finland, of course.
