How did some of you set up your party?

[Xurts]

I usually use Cloud, Tiffa, Barret for my final party but they are about the same level as everyone else. I usually have Cloud use the majority of the magic materia and Barret use the steal, mime, etc materia and Tifa heals. I havent played in awhile so what is the upgrade on the premium heart?

The Premium Heart's power depends on how many times Tifa missed the slot wheels during her Limits.
