Help Greater Sphere Farming

[Flummox]

Greater Sphere is an Arena monster that is the only known dropper of Luck spheres, necessary items for endgamers. Hes pretty tough though, took me a while to get a decent strategy to farm him. I'll explain my method and then perhaps people can describe how they get around him.

My setup: Yuna, Wakka & Tidus are my main 3, 255 Strength, Defence, Agility and accuracy, the rest of the stats around 100-150 and with roughly 23,000hp each. All 3 have Celestial weapons. I set their overdrive modes to Victor, go and fight another monster ( I like to fight one eye because he drops half decent weapons/armour ) twice, with the triple overdrive of the celestial weapons this means that they have full overdrive, I then go and fight Greater Sphere and do a blitz ace and a perfect attack reel and that pretty much finishes him off. Rise and repeat.

Comments and tips welcome, how do you farm greater sphere?

EDIT: This also helps with defeating Earth Eater (dropper of fortune spheres)

I used a similar method but just set the party's overdrives to stoic as greater sphere can do some pretty decent damage, so Wakka and Tidus can execute attack reels and blitz ace frequently. It's a good idea though fighting one eye in between battles for triple ap weapons (good to sell + good if you want triple ap then add triple over drive then over drive > ap) or hoping for a rare drop of dark matter. I eventually hit the 255 luck mark (over kill I know lol) maxing my sphere grid.
