Do you honestly think Troy is a greater threat than Kim? I don't. I feel Kim is a far greater threat because of the numbers she has.I agree that keeping Kim, Chelsea, Kat, and Sabrina around is the best shot at beating ONE PLAYER. But keeping Troy around is the best shot at beating AN ALLIANCE.
Even if Alicia and Christina flipped and they get down to a F5 with Troy, Tarzan, Leif, Alicia, and Christina, it will STILL be everyone against Troy. No one (and that would include Tarzan and Leif) will want to be sitting next to Troy at FTC. Troy would have to win out. Already we've had our share of lame challenges and my suspicion is we'll probably see more which is why I'm sticking to my claim that a Troy IC run to the end is extremely unlikely.
I'm glad we won't see this because of my dislike for Alicia, but I feel she wins a F3 with Tarzan and Leif. With the eight player remaining I see no F3 scenario where Alicia wins.
