Favorite MW3 class setup?

Hey guys, just seeing what kind of setup everyone uses. :P

I personally use the P90 with 2 attachments, silencer and rapid fire. Secondary weapon is Javelin. Perk 1 - Sleight of Hand pro Perk 2 - Assassin Pro perk 3 - steady aim pro.

It really tears nubs up. :)

My favorite so far is.

Primary Weapon : PP90M1 with kick and silencer.
Secondary: USP with silencer
Explosive: Setmex sometimes bouncing betty.
Tatical: Stun
Perk 1: Blind Eye
Perk 2: Assassin
Perk 3: Sit Rep

I normally play hardcore, so perfect set up for it imo. I normally use assault kill streaks, UAV, Pred and Chopper. Some times switch chopper to Assault Drone if im having a good chain of games.

Scar-L Silenced w/ Blind Eye Assasin and Dead Silence

I have been using the PP90M1 with kick and extended mags, USP, Semtex, Stun Grenade, Scavenger Pro, Hardline Pro, Dead Silence Pro and my Strike package is the specialist with Slight of Hand Pro, Assassin Pro, and Steady Aim Pro. I find it to work really well.
