Halo 3, double EXP and rocket kills for me

Just a quick reminder to all the double experience point supporters of the world, Bungie recently flipped the switch on a new
Halo 3 Rocket FFA playlist as part of yet another double EXP weekend. This limited availability matchmaking playlist will only be available until Monday, June 9th, requires the
Legendary Map Pack to play and (of course) will award you double EXP with every rocket win. Though, your multiplayer
Halo 3 achievement progress will have to wait, because this FFA playlist is NOT ranked meaning you cannot earn any achievement goodness. And that overkill would have been so easy ... humph.
So, what's it going to be? Double EXP in
Halo 3 this weekend or
double XP in Call of Duty 4? Decisions, decisions, decisions ...
