I think I agree with everyone on this with adding a few more. Carpet/diamond pythons good choice. Boas are great, like mentioned you can get dawrf and cool color morphs. My favorite but under rated is the woma pythons. Or if you have the money to spend and want something no one has you could get a black headed python. About the size of the boa without the girth. I'm a big fan of Australian snakes and most of them if cbb are great
