i dont like ball pythons for the simple fact of their feeding habits. when i had balls, they were usually off feed, but my boa has never missed a meal. you have to ask though, what size are you willing to have? male BCIs will average 6-8ft, while females are 7-9. i love boas, their so great. they have a great temperment too. whatever you get, make sure you get it from a breeder, not a petstore.
