I have a front BB7 already, it's a good brake, although, I don't find it any more powerful than my original MX1 that came with my bike. Both 8 inch front rotors, and I found that when the Mx1 was working well, it had more power than the BB7's do.
I need a rear brake that is strong enough to do some trialsy stuff. My current rear Mx1 (6 inch) doesn't have the power to lock with my weight in the rear. I'm not really wanting to go with bb7's.
