I'll be getting a ball python for sure... but will have room for a second. Was aiming for a Mexican Black Kingsnake, but I just really love the look of a python, their head specifically and larger girth specifically.
I like the look of boas as well, will have to look at some of the smaller varieties. I've generally stayed away from boas because I've heard they have a harder bite. Not so much for me, but if one of my two boys get bit I'd never hear the end of it from the wife.
Kenyan Sand Boas burrow too much, I guess. I want something that's a bit more of a climber... climbing the branches I hope to throw in there. Will check out the Rosy boa, though.
