Candoia Aspera are really neat, yes. I haven't had a chance to keep one, but to my understanding they -are- a bit mean, yes. This is partially because the vast majority of these animals are still WC. Few, if any, have managed to breed them in captivity.
IF you can get your hands on a CB animal that you like, I'd say go for it...
In regards to size, they really are on the smaller side, you've no reason for concern.
