Advice for a Junior, please!

I go to a pretty small school with 4 established sororities and a 5th one is colonizing in October. Anyway, I started the recruitment process this week and after two days of meeting with all the different girls I only felt a connection with one of them and naturally I picked them and they dropped me. I don't know why as I had great conversations with many of the girls. My only guess is that they weren't looking for an upperclassman because I can't think of any other reason. Naturally I was very upset and decided to drop because I didn't feel good about the other groups AT ALL. I'm a commuter student and I want to get involved in campus and have a great bond with some great girls but the very limited option at my school was a disappointment after I got rejected for reasons unknown. My question is...do you think it'd be a good idea to go through the recruitment process with the sorority that is about to establish itself? I think I'd have a better opportunity to get a bid as well as be a part of the process of starting a new sorority. Do you think it'd be a good idea for someone who is a bit shy at first, but very motivated to get involved and make great friends?
