What is the best Call of Duty: Modern Warfare 2 cl for me?

I am a level 70, 10th Prestige (did not hack, I'm just a noob) and as my primary, I use the AK-47 with a silencer and grenade launcher. As my secondary, I use a SPAS-12 with the silencer and red dot sight. Perk 1 is Bling Pro, perk 2 is Stopping Power Pro, and perk 3 is Ninja Pro. Equipment is Claymore and special grenade is stun grenade. Deathstreak is Final Stand with the killstreaks as Predator Missle, Harrier Attack, and Chopper Gunner.
