One rule I learned is that usually, though not always when morphs are involved, BCC should have 15-22 counted saddles from snout to vent, and usually have very clean saddles too with a particular shape (oftentimes looks like a batman symbol, but not always). BCI generally have 22-30 saddles. In all cases where I knew for sure which the boa was, this held true so far. She looks BCI to me, very much like my own. The only BCC I visit regularly has thin, clean, pinched saddle patches and a more golden tone to her overall rather than a purply brown, greyish, or tan and pink.
