in my opinion, getting a Colombian or some form of Central American Boa from a long established captive bred and born line, such as one from Gus, these animals are a bit more hardy and can be more forgiving to the novice keeper.
Many refer to boas as red tails, but the only true redtails are bcc. Colombians are just Colombian Boas.
BCC are less forgiving... these are generally for the more dedicated, experienced hobbyiest who has 'fine combed' all his techniques and experiences.
If you haven't 'mastered' all aspects of caring for a colombian, I would not look for a BCC.
Recent imports and farm bred BCC or Central American Boas can turn out well and be hardy specimens, thing is, many times they come in infested with parasites which cause many other problems.
Even a good feeder can be more unpredictable, nervous, and/or flighty, just because of the fact that they are wild animals, and/or nowhere near as domesticated as a Colombian Boa from long CBB line.
Hope that helps.
Take care, Joe Rollo
