Final fantasy x

[Guest Crazy Dan]

I have been playing this game for a couple of weeks, and i am getting pretty far, but I have come to the part in the game where you fight Seymore on the mountain (I think it is the third battle, where he has just killed the Ronso race, and such)  And I am having the hardest time beating this guy... so I am asking any of you who have gotten past this battle, what is the best strategy to passing this boss fight...

Have the Auto-Med ability on at least one of your characters and hope for a lucky fight.  I've literally seen Seymour rip into a party in one fight and then get his ass kicked in under eight turns in the next.
