If it wasn't a BCI or BCC boa what would it be?

If we can't pick a snake in the Western Hemisphere, that rules out Green Tree Pythons which would have been my first pick. But....

Emeralds are from the Western Hemisphere. Green tree pythons are from Australia and Indonesia. So you'd still be in luck if you wanted them and couldn't choose a snake from the western hemisphere for what ever reason.

To the op. if you want a good sized, relatively easy to keep and handle snake than a bci is pretty much the perfect choice.
