I know what you are saying... It is more gratifying to kick booty with some gun that people normally think of as sucky so you can say things along the lines of "I owned them all with a Skorpion w/ ACOG!!" I am going to try for red tiger on the Skorpion this prestige just because I never see anyone with one! ANYWAY... here is my answer to your post:
Skorpion W/ ACOG Bomb Squad, sonic boom, and eavesdrop

or
W1200 W/ Red dot C4, sleight of hand, and Iron lungs
If you are really hardcore, pick a noob tube then change to a different gun setup BUT DON'T PICK A PERK 1 ON PURPOSE!!
