Maybe this moves towards clearing BB, but I can easily see Sarcastro being an opportunistic scum and scoring on that word train. I don't really trust him with that.
If you want me with you BB to keep an eye on me, and so I can keep an eye on you, Sarcastro, and Gameshark, I'll go with the everyone in one spot strategy.
However, I'd love to get a weapon unlike last game so I'm not helpless in an endgameish scenario.
