Its any two primary weapons with overkill. Most of the time I roll with perk 1 as 3x grenades, perk 2 as stopping power (smg's, assault rifles, snipers) or double tap on my light machine guns, and shotguns. Perk 3 is usually deep impact, steady aim, martyrdom, or iron lungs depending on which primary weapon I am carrying. Like on my snipers though, I carry a sniper rifle, with stopping power and iron lungs or deep impact. Then I carry the gold desert eagle as a secondary weapon. If I get in a map and have to move around a bit, I will ditch the deagle for some dead guys gun like a m4 and shoot everyone up to get where I am going.
