For my perfect save, I have two armors I consider to be "ultimate armors".

One is Break HP Limit / Auto-Protect / Auto-Shell / Auto-Haste. The other is Auto-Med / Berserkproof / Confuseproof / Deathproof. Sometimes I wonder whether it should be Deathproof or Stoneproof, but I picked Deathproof in the end. Anyways, the first is basically for fighting Nemesis, and the second is for fighting bitches with status attacks. The second armor is impervious to everything except Stone, and the first is basically an auto Super Mighty Guard.

Anyways, what would you consider your ultimate armor/s to be? Specify what version you're playing too, by the way. I'm playing the North American release, so I don't have any of your nifty PAL extras. :\
