The other, and most important thing, to remember with BCC's is that they aren't as easy to care for as BCI. A BCC will get stressed from imperfect husbandry a lot faster then a BCI. I've heard many times of BCC getting stressed and dying from moves (different housed or such) and also from inadequate sized caging. They are not a first time boa owner snake, imo. I'd go with a BCI for your first time.
