Trimming the Buff List

I only play with a 19" 4:3 monitor. When I'm in a 25man, the buff list gets pretty big. I have a bunch of new buffs occur during combat that I already have Power Auras or NeedToKnow set up to visualize. Specifically: Lock and Load, my Meteorite trinket procing, my Replenishment, Expose Weakness, etc, etc, etc.

I would like to exclude those buffs from showing up in any buff list. I already have them covered. What addon can help me here?
