Brain vs. Brawn vs. Beauty

I have been watching Survivor this season, which I haven't done in a long time. What intrigued me back into watching it again was the tribes they created. They created 3 different tribes, one filled with people that all had really high IQ's (The Brain Tribe), one filled with really strong muscle-y people like cops, an NBA player, and more (The Brawn Tribe), and one filled with models and other pretty faces, (The Beauty Tribe). I thought this was so interesting! I have to watch it to find out who wins! At first the Brain Tribe has been HORRIBLE, but now that there's only 3 left and they merged, they are in a very good position to make it to the end. I personally think someone from the Brawn tribe is going to win though. They have an even bigger majority on their tribe, and when they merge again will most likely win all the challenges. It's logical. I don't want to make any guesses as to who specifically will win though. In that case, it's all about likeability, and that still remains to be seen.
