I use Hinata, Kakashi, and Kabuto and they seem to work very well for me. I c*ually get around a 34-hit-combo then a 20-hit-combo within the same round as long as no one is acupunctured or otherwise paralyzed. I put Hinata right up front, Kakashi to the right and center, me in the center, and Kabuto right behind me.

I use Hinata's attack first, Chidori blade next round, Kabuto's attack, and then Kakashi's. I keep cycling through those as they become available.
