Grinding: Who do you Grind with? (leveling)

[BellaTheDead]

Lulu Auron and Tidus Normally. I never really switched party members unless I had to or one was dead. I eventually ended up picking those three as my favorite characters and always us then if available

[scorptatious]

For almost the entire game I used everyone for grinding. But as I as I got close to the end of the game, I found myself mostly using Tidus, Auron, and Lulu. As they become very big damage dealers by that point. Although I also liked using Yuna and her aeons as well.
