Well, good luck with whatever you decide. I don't know your school, or could tell what you "let out of the bag."
One thing that I think would be a definite benefit of Formal Recruitment would be that you would visit ALL the organizations. As folks here will tell you, be prepared for tougher cuts as an upperclassman, etc. And still keep an open mind, since like you said, at any house, you might click more with different sisters than ones you had this (informal) time around.
So I'm sorry it didn't work out as you'd hoped. Good luck with whatever you decide. I personally joined via partially structured/informal recruitment, and there are times when I wish I'd gotten to experience the huge production that is Formal Recruitment as a PNM.
