I have all of Wakka's overdrives but I never really use them. To be honest with you, I never use any of my player's overdrives (except Yuna's_ since they already always take away 99,999 anyway. I have all their Celestial Weapons, and all their stats are maxed. Well, enough bragging, I still need to finish FFX-2 completely - I'm stuck at 94%.

Just thought I'd put in my two cents. Thanks for the read:
