Would anyone be willing to provide gen Sam and Dean-centric recs? I don't sift through them as much as I do other things, so I know I've missed a lot. I'm willing to read a whole lot of genres, but I especially like serious crack. Like, that one wing!fic where there's gore and they call in a bird expert. Case fic is cool too. As are creature/robot/whatever AUs (I just would like to avoid bashing of other characters).
