Squall, Irvine, and Rinoa have the capabilities for the most doin'est damage while still being ones that don't annoy me (hence, no zell).

Selphie sometimes goes in for irvine. I don't really like zell *or* his limit (too much work!) so he's rarely in my serious party (he's in it right now, but I"m just levelling squall up, so it doesn't matter, 'cause he's ko'd anyways xD) quistis is sometimes.
