I agree with all of the other posts before mine. It's very true that the "number one" house may not be the right one for you, or it may be, who knows? My suggestion is to keep an open mind during rush, and you will know which one is right for you. Hazing is not condoned by any college panhellenic association, nor by the university community, which is the plus to joining a "National/Inernational" organization. I'm not knocking locals, as I'm sure they have their benefits, but I know they don't have the same type of governing bodies that IFC/PHC GLOs do.
Best of luck to you, and be sure to check out each of the houses international/national websites, they give you a great idea of how the organization is as a whole.
