Right now, I'm using a 5-7-9 killstreak setup (Predator Missile, Harrier Strike, and Pavelow), but I wanted to know what you guys use. Is there any killstreak setup you find better/more helpful?
About the 5-7-9 setup, it works well for this reason: Get the five, and then call the missile. Missiles often get doubles or even triples, scoring you your Harrier. Harriers then either bomb a person or two, or the lingering one kills some people with its gun, getting you your Pavelow. As you all know, Pavelows cause massive amounts of carnage on the battlefield.
