A few days ago, I re-read Maximvs' video tutorial. About 3 days ago, did a BB with a friend while recording it. Lag was obviously horrendous due to the recording process, but the two of us pulled off a pretty nice BB - only 14% damage total. A couple days later (now) I've managed to get the whole thing posted, in two parts.
