What three characters do you use?

As long as I have Cloud and Tifa I'm happy. I never really use Cait Sith

I've just started a new game & at the moment I have Cloud, Barret & Aeris... coz I know I will HAVE to have Aeris in my party at one point... & then have to use Tifa in my party sometime after her.

But, after that, I usually have Cloud, Barret & Vincent. I may change it this time though.

Only Cloud and his BIG SWORD. I leave the rest dead for aesthetic reasons. They are just unbearable compared to the magnificent BIG SWORD that Cloud uses.
