UF Sororities (a very important question)

[Gatorbaby]

Nearly all of the UF sororities are solid (100-150+ girls it seems), so that's not a question. But, which sororities are competitive to the degree that a rec is nearly required to be considered? I've tried to pick up recs from as many sororities as possible; because it's getting to be crunch time (less than a month before Formal Recruitment/Rush begins!), I'd like to know if there are any extremely competitive sororities that I need recs for should I even be considered or stand a shot at being competitive for these groups.
Thanks! (For extra info, I'm an incoming Freshman, and this is my first time Rushing)
