if your just starting the game then fire main would be great ,even light main is ideal since you can build a team around him with ninjas such as HInata,sasuke,guy,kabuto etc , you can go wind in the later part of the game.For e.g if you get some1 like sg naruto..As for treasure it really depends on you .If you wanna play around cancer you can go Roshi , Gnw treasure has great ninjas and can work greatly if you opt for light main since most of em are swordsmen , Not to forget about land of lightning also , since in 210 seals you can pretty much build a whole team,consisting of ay 3rd ,samui and omoi . rest of the treasure are something i dont advise.Talking about your lineup it would be much easier if you can post the screenshots of the ninjas you have.
