Friendship fics?

[kutsuwamushi.livejournal.com]

Hi all. I have a very obvious request, but I'm not familiar with Star Trek fandom and I don't know where to start looking.

I'm looking for friendship stories starring Kirk and Spock. By friendship stories, I mean any story that gives attention to their (platonic) relationship. I'm most familiar with TOS but I'm not too picky about canon version.

So what are your favorites?
