I'd rather use Dual Pythons. Double CZs are good, but they lack the fire power and the Pythons are like a shotgun in close range. They are mostly the same as you know them from the Magnum in MW3. Very effective if you are going to play on Nuketown and he's sitting in one of the buildings.
If you are playing against someone who doesn't have a headset I would also recommend Tac Mask Pro especially when playing on Nuketown. Just throw out your stuns and you can already see the direction where he is moving. Most people don't expect someone using Tac Mask pro or don't even know it's effect. You might surprise him there with one or two kills while he thinks you are flashed/stunned.
Don't quote me on that one, but I think flashbangs have a larger blast radius + they are more effective if he starts camping. Don't forget : throwing stuns is much faster than throwing FBs in Blops.
If you are going to play very defensive use your claymore. Otherwise I suggest a jammer or a motion sensor if he isn't running Hacker Pro. Claymores were pretty strong tools in Blops. Their set off charger is way faster than in IW's games.
This is just some other tactics you could use if you are allowed to change your class during the game. Gotta keep it flexible

Otherwise I approve of War Hound's set up.
As a quick summary :
FAMAS RDS, AUG RDS or 74u rapid fire
Python Dual wield
Frag
Flashbang
Jammer or motion sensor
Lightweight (Pro)
SoH (Pro)
Tac Mask Pro (!)
