going through formal recruitment again as sophomore?

I didn't get an invite back for pref night to the house I REALLY wanted this year (freshman) and I got discouraged and dropped out of formal recruitment even though I had two great houses left. I think I was just too obsessed with wanting to be in that one sorority. So anyways, I kind of want to rush again sophomore year and keep more of an open mind but I'm nervous. Like should I even? Will they know/remember if I rushed freshman year?
