BRBs are great, but it is important to understand that they have specific husbandry requirements above and beyond most boas that must be met. Especially as babies they require incredibly high humidity. This is an absolute must. If humidity dips too low for even a small amount of time they can dehydrate and die. If you live in an already humid area, and are committed to keeping the enclosure humid, it's not a big deal. But if you know that it's going to be a struggle to keep humidity up, I would choose a more forgiving animal husbandry wise. Also, keep in mind that high humidity enclosures require more cleaning and mold prevention.
