Very interesting. I especially liked that you picked up on Rufus's evolution as a character. I think the way he changes is facinating, but no one else seems to be interested in it.

Even taking the BC Turks into account, I think Tifa would be the female that would suit Reno the most. I tend to pair Tifa with Cloud because I'm a canon whore, but Reno/Tifa has a wonderfully refreshing lack of angst to it.
