I'm looking for a fic I started reading in which Kakashi tests his team's affinities and Naruto reveals that he can, to some extent, sense their affinities by the 'feel' of their chakra, or something along those lines. So Naruto is a natural sensor type. Anyone know the name of this one?

I remember the plot of the fic - might help you narrow it a bit - but not the name, Kakashi goes back to the past and trains his team properly and it's revealed that that's the case? I think the two characters in the "main character dropdown box selection" were Iruka and Kakashi and I did it randomly at the time to see how many their actually were out of bordom.

 

That one might have been TimeMixUp by Lucillia? Not a hundred percent though, and can't be arsed to go check. It was a Kakashi time travel one though.
