Troyzan looks like he's just along for the ride though, doesn't seem to have any real involvement with strategy.
I'm between Birdcage and Aubry Huff I think as for who I'd like to see win.
Now that the model/gymnast/pony whisperer/pilot is gone, nobody truly detestable left to root against.
I think the legit shots to win are Birdcage, Aubry, Brad and Cirie. Sarah has an outside shot, she just made a big move and has the Blind Michaela voting advantage still, but I don't think she'd fare well in front of the jury.
Tai may make the final 3, but he will suck answering the jury. Sierra Bullock could probably only win if seated with Michaela and Troyzan.
Michaela as noted before is too volatile, may be a great person to take to the end cause she won't get the votes. Andrea has pissed enough people off she won't win.
