Beating with bare hands was the best option on there...

But!!! Lionheart (Squall) and Grand Lethal (Zidane) were both kickass limitbreaks/trances. Have you finished playing FFIX or even played FFVIII? I think those had the best limits/trances. Especially FFVIII, Zell's Duel was insane. It was up too you how much damage was done. Cast Aura and Meltdown, then WHAM!!! You could easily Ultimecia in one turn (If stat requirements are met)
