Even if it comes down to Jemmy and Rollo for pref, just go to the parties. You have nothing to lose, and if you still feel like you don't fit into either of them, then drop. Plus, your feelings could change during round 3. I actually wasn't sold on the chapter I ended up joining until round 3 (granted I felt so-so about it before, and not negative).
I am really interested to see where you end up because I think you are at a school that I would have loved to attend! There's always grad school I suppose
