Grinding: Who do you Grind with? (leveling)

[loaf]

yeah but im on about after you have finished the game, not many people stick to using everyone once the game is finished.

You asked who do I grind with, not who I use when I max everyone's sphere grid. In that case I use the best team in the game, the only 3 characters who can swim underwater. Tidus, Rikku and Wakka.
