all Main is good, but u need good ninja for make great line up. Im MB, but now i change to water since i get ningendo.

for water main (im lv 83) i use
x x x
x ningendo AF
gakido darui x

talent 4,4,2,4,2 pet Dog Of Hell.

u just need have high initiative and win all PvP, i see u have good power for lv 79. just make u'r all refine at move 1 is lv 7 / 8, move 2 (if nuker ninja like me) have refine lv 4 - 6, and move 3 have refine lv 3 - 4.

for now i like water main cos have good crit and dmg, and have misery just need 20 chakra. so i can counter enemy if they have healer/canceler debuff with my ningendo at round 2.

but, if u want use hidan i can give some advice.

x x x
chikushodo MB x
Hidan Bee x

talent 2,3,2,1,2 or 2,3,2,1,3. pet gamaken/gamachu

catch him in tendo treasure xp

if u give much tag to u'r enemy, u will get easy win xp cos u'r hidan will make they all have low life
