Has anyone done any special runs?

I've done:

Enough normal runs that I've used every job at one point
Low Level Early Class Change
Early Class Change
4 Black Mage/Wizard (which I didn't actually finish since Chaos kept healing himself faster than I could do damage and I couldn't beat him)
4 Warrior/Knight
Red Mage Solo run (my current run)

All on the GBA version of the game (yeah I know it's easier than the rest but w/e).

Has anyone else done any special runs?
