Final Fantasy VI — best party for Kefka tower?

I'm finally at the final tower in FFVI. Have 12 characters maxed but the dungeon splits you into 3 parties of 4. Looking for advice on optimal compositions for each path.

Current loadout I'm considering:

• Party A (Kefka path): Terra, Celes, Sabin, Mog
• Party B (mid path): Edgar, Locke, Setzer, Strago
• Party C (lower path): Cyan, Gau, Relm, Umaro

Anyone done this with Gogo + Mime cheese? Or should I just brute force with Terra+Ultima spammers?

Solid baseline. A few tweaks I'd make:

Strago is dead weight in mid-path — his Lores are great but he can't tank. Swap him for Mog with Dance equipped (Snowman Jazz wrecks the ice statue).

For the Kefka path, you absolutely want Celes with Ragnarok (not the sword, the esper) for Ultima. Pair with Terra's Morph if you have it. Sabin's Bum Rush still hits the cap, so he's fine.

And no, don't bother with Gogo+Mime. Cheese is fun but the fight is so short that setup time exceeds payoff.

Echoing crt_kid on Celes + Ultima. I beat the final form with her solo on my last playthrough using just Ragnarok+Genji Glove. It took 6 turns.

One thing nobody mentions: save your save state right before the final triangle. The cutscene is unskippable and you don't want to redo it if you wipe.

Different take: this is your last save before credits, so use whoever you actually enjoy playing as. The fight isn't hard if you're level 50+. Don't optimize the joy out of your favorite game.

That said, Umaro is genuinely useless here. Sorry Umaro fans.
