your main team seems good, tho ik similar winds with same format do more:

*x
karin-main-hinata
chiyo*

if you wanna use kankuro with ur bd i'd use it with sasuke (3*) not chiyo ... up to you if u wanna try testing the puppet's durability (and extra guard in first rank) or do kank-x-hinata to keep it safe. but those 3 combo pretty well together (and well with kiba too, if u wanted to make a non-main team, but i get why hinata would be on ur main team) ... do u not have gnw kankuro? i'd use him over regular kankuro

world boss strong wind ninja team is best with wind enhance, tho feel free to throw in say someone like 1010 who does real dmg off high combos that u can initiate with gust dance for example .... at ur lvl u might still be dying from ground slaps and stuff so use clones to max advantage. u should 3* sasuke and naruto soon.

arena lineup someone on forums once recced:

*x
main-kakashi-hinata
kabuto*

and that works pretty well ... put all ur clone spam abilities on and u can win a fair few just out healing and timing out them unless they got a really good single target assassination combo thing going on
