fairly academic fraternities

So I'm an incoming transfer this fall ('17). My past university's Greek life was pretty lacking, but USC looks like it has more to offer. I'm a double major and put a pretty high value on my grades, but I also love to party, so I guess my question is, what fraternities have a great balance between the two? I'm not super fratty. Athletic, but I'd take a tshirt over vineyard vines any day.
