If you buy a male and raise it conservatively almost any BCI will do.
I have a male, Barranquilla, Colombia boa constrictor that is approaching 6 feet long. He will be eating 1 pound rabbits or large quail, or large rats.
I don't need to feed any larger than that. But I'm raising him to be a larger male. As in,,,, he is not a breeder, just a shoulder pet.
I bought this beautiful, Gus Rentfro produced boa from Legacy Reptiles in 2013.
