RoW Teams are very effective at least as far as ive seen on my server ... but ... dont use Kisame ... he is not rly good you would be better of with something like the Curse mark team :
X X X
Sasuke Main Kimimaro
X Jugo X
There are some guides for thisteam on the forums:)
jugo can be sweept adn gives a shieldto curse mark ninjas

Or something like:
Kabuto Main X
Sasuke Kimimaro X
X X X
also work nice if you want a healer
