I've used this formation for a while when I was Lightning :
Tobi + Midnight Blade by Kyutaru

It wasn't bad at all, but I changed it a bit since I don't like having Tobi in the front row. I used it this way :
X - Kimimaro - X
X - Main - Sasuke
X - Tobi - X

It worked pretty well in battlefield, but Sasuke should not be in front in most lineups. However, I prefer Tobi to Sasuke, so I did that :p
Kyu's got more experience than me though, so his version might be better. Anyway, judge by yourself :)
