I would guess BCI. Based on a saddle count (if I'm guessing correctly where the vent is...) of 21, as well as the very dark red/brown tail saddles. Typically BCC's have 20 or fewer saddles, and retain the striking red coloration on the tail, even as they mature. Really it's impossible to say for certain, though. Regardless, he's a beaut!
