Fic recs?

TOS fandom is a very, very confusing place - as near as I can tell, it hasn't exactly settled down on LJ at all, and much of the fanfic is in print zines rather than online. Fanfiction.net still seems to be the easiest place to find fic, which is, um, not necessarily ideal. While I have been gleefully devouring the Orion Archives, I thought I'd just issue a bit of a plea, because I know some of the flist (including a few new arrivals thanks to that crazy Amok Time recap I did - hello!) are much better acquainted with this fandom than I am.

I'll read any and all pairings, but I'm a gen fangirl at heart, and quite possibly my favourite thing ever is action/adventure-type stuff featuring the Big Three. Any recommendations? Archives I've managed to miss?

Thanks very much! :D
