I like B&B, ended up getting it in a sort of manic phase of spending way too much money on stuff I probably won't use (Firecracker is already $200 I'll never use and never see again). However, I think it's really only great for exactly what you described, annotating into FA. It does good on the name in that it truly goes "beyond" first aid and pure step resources. Otherwise, I'm not sold on it as a resource. He's really just one guy, and compared to a lot of more official resources out there (and completely unofficial resources, like anki decks with ripped images), he's extremely limited on graphics because he either doesn't have rights to them or can't make them himself. It ends up being a series of long, pictureless slide presentations. Also, he talks/covers material far too fast. I'm able to keep up with Sattar on blank pen and paper easily, but I get a headache from the constant stopping to catch up on notes with B&B.
Personally I think seeing diseases presented in a clinical format, as they are on the boards, works best for me. I do as many questions as possible and look up what I don't know, even if it's wrong answers I knew were wrong (but didn't know why). I get these from BRS, Lippincott's, Kaplan books, Robbin's Review, etc... all of which I found online for free.
