I will also be rushing as a sophomore. I don't see not knowing many of the girls a disadvantage. I don't know that many either. Out of the 4 sororities at my school, I am friends with just 1 girl in two of the sororities and really good friends with 3 in another sorority. One of my main goals at rush is to meet a bunch of different girls, make great friendships, and of course get a some wonderful sisters!! I watched my good friends go through rush as incoming freshmen when the only other people they knew were each other. The only advantage I can see is that by knowing girls in sororities, you know what the sororities involve(i.e. certain sororities' standards, what type of community service or social parties do they have). But you can always ask these type of questions during rush.
