fraternities more into brotherhood/sports/academic

What's up, everyone. So I'm an incoming Freshman looking to rush a frat. I'm mostly interested in the frat for the social aspect, and I'm not a huge partier (though I'm definitely open to raging every so often). School is definitely the #1 priority for me, and as a Mechanical Engineer, I definitely want to take advantage of everything Cal has to offer, be it research or clubs. I've been working in a lab on campus this summer and plan on joining some engineering competition team(s), so I'm definitely looking for a frat whose pledging isn't too time consuming. I played soccer and lacrosse in high school, so I'm definitely into a frat that is active in IM or club sports as well, since I definitely want to try to continue one of the two in college. TL;DR I'm looking for a frat that isn't too partying heavy but has brothers active in sports and academics.
