Ive just started reading a NaruSakuSasu Fan Fic and I gotta say it's pretty good, as long as you can accept some yaoi. It hits the charcters personalities pretty much dead on, the only thing is that the fic was started before the Naruto Sasuke fight at the valley of the end. So you see pre-time skip personalities but the author has been keeping their personalities true to their current traits.
Dont knock it, at least give it a look.
This is the first series, there is the second one after this, and the third one just recently started.
