Do you camp on MW2:.............?

I do once and a while I use: scarch/W/silincer,perks:1 scavenger 2 cold-blodded 3 commando(in case I have to make an ecscape) killstreaks: predator missle, harrier, chopper gunner... so if you camp what's your killstreaks,guns,perks etc. And if not how do you deal with campers
