I'll chime in my 2 cents:
I don't go to UF but I would assume like all sorority recruitments, it's a draining 4 days - 1 week. Before you consider that option, really ask yourself, is this something you still want? Do you really want to be in a sorority and most of all, why??? Also, do you really want to go through that huge emotional investment for that amount of time? It's really up to you and then if you a strong feeling then really consider re-rushing, but then look at the odds of a sophomore getting a bid at UF, there's probably someone at UF on here who can give a better answer.
Although, at my college, almost every junior and senior that went through recruitment and received bids. Then again, my school does not care about year as much as other colleges would. Also, then again, not many people at my school re-rush b/c they find something else to do or realize that "thrill is gone" to an extent.
Good luck in whatever you decision about re-rushing
