@EverythingBloo: 30% participation in varsity athletics or intramurals is a bit low for a school with just 1600 or 1700 students.
At Furman University the participation level is in the range of 65% to 70% with about 2.700 students. Plus, better weather. Gorgeous campus.
OP: Based on your posted self description, you are a very strong match for Furman University and a weak match for the other two schools. (I prefer not to elaborate, but feel free to PM me if you need further explanation or have any questions.)
What sport or sports did you play ?
As a self-described sporty-preppy individual who leans conservative & attends church on Sundays, wants strong academics, and enjoys volunteering, Furman University appears to be your near perfect match school.
(I have no relation to Furman University, nor do I have any interest other than addressing OP’s concerns to the best of my ability. But, I am familiar with all three schools discussed in this thread.)
P.S. Cautionary Advice: Make sure that you deposit at whichever of your current schools is affordable & preferable to you at this time. Also, I am not certain which school is best for econ majors.
