changing my name

well i just got some money from late christmas preswnts and stuff, and i was thinking of using it for getting microsoft points for a name change. since i probably will do it to make the clan more offical, and so that you guys didnt change your name for nothing. but what should i change it to? Ace RushZ maybe or Ace Rush i dunno. so please post a reply on what you guys think and if you have any name ideas.
