What college would be a good fit?

I'm a high school senior and I'm trying to figure out a school that fits my wants, but I'm having difficulty doing so because I'm unable to visit all of them. I'm a pretty good student; I have a cumulative GPA of 4.22 and I scored 1970 on the SAT (but I'm going to retake that). I'm also very social and love sports. I want to go to a school that's difficult to get into and has good academics that will prepare me for the work world, but it is also EXTREMELY important to me that I get a good college experience. I want to go to a school that also is very social and has a good, but not completely overbearing party scene, and also has a lot of school spirit and emphasis on athletics. Size doesn't matter too much, but I'd prefer it to be a medium sized school, so anywhere between 5,000-15,000. So far I'm looking at USC, UCLA, Duke, USD, Boston College, LMU, USD, Rice and Northwestern. I understand that these are some incredibly tough schools to get in to, but I was wondering if anyone has any suggestions that fit my desires or if anyone knows anything good or bad about the colleges I listed above. Any help would be so amazing; I'm really getting stressed at this point!
