it depened on what time in the game. Near the begining, it was Tidus, Yuna @ & Lulu, round the middle, twas Tidus, Auron & Kimahri/Rikku and now, i would mostly use Yuna, Kimahri & Wakka, because then i have Blk Magic, Wht magic, Haste/Slow-ga, strength, speed, piercing, steal & break damage limit.
