Black ops 2 best SMG class

If you like to run and gun in call of duty im going to tell use witch class i use and i think is the best SMG class in back ops 2 let me no what use think of this class.

PRIMARY GUN
PDW-57
This gun has a huge clip of 50 rounds. It also has good range and with the right perks and attachments is a beast of a gun.

ATTACHMENTS

Quickdraw
Suppressor


PERK 1
Lightweight
Ghost

PERK 2
Toughness

PERK 3
Dexterity
Extreme Conditioning

With these attachments and perks you will be running around the battle field faster than most of the enemy. With the Quickdraw attachment and the lightweight perk on if you come face to face with 3-4 of the enemy you will most likely have them all killed before they can even look down the sights. Please leave a comment and let me no what use think of this class setup.
