thats a great site.
also look at the widows peaks on the saddles, some of the classic bcc's show really good ones, and none of the bci's really show any. there's also quite a difference in head shapes. they're like anything, once you know them well enough you can kind of pick them out really quickly, even from a side shot of a body cue style.
gus rentfro breeds some beautiful boas and he breeds a lot of bci localities, he has awesome pics and info
