Oh yeah, target filters.. I use up/down on the party list and l2/r2+l1/r1.. But also have special filters for "enemies only," "friendly PCs/npcs only," and "duty/aggro mobs only." Filters are nice since you can use soft targeting with left/right and avoid cycling all the random environmental stuff. I'll also use l1+up/down if I want a specific mob on the enmity list.
