dropping now and re-rush as sophomore?

Hi guys,

I'm currently in a good middle-tier sorority with really sweet girls. However, even after being as open minded as I possibly can, I still have this nagging feeling that I belong more somewhere else. I have a lot of friends in some of the more "upper" sororities and I'm wondering if I drop now and re-rush as a sophomore this Spring, if I would have some sort of a chance to get into a different and decent house? I'm not trying to get into one with "better" rankings at all but I really feel like I don't fully belong in my sorority but I would still love to be a part of the greek system.

Even if I don't rerush, should I drop anyways and become a GDI or at least stick it out til Recruitment in the Spring?

I'm just in such a dilemma here :(
