Black Ops -Sub Machine Guns

I myself do not use many sub machine guns in Black Ops. The only gun I have used that is a Sub machine gun is the AK47u, this is a really popular gun amongst alot of gamers. I don't use this gun often so I don't know much about it. The other sub machine guns, I have never used include the skorpion, mac11, uzi, pm63, mpl, spectre, and kiparis. I wouldn't recommend using submachine guns in many game modes besides free-for-all or a game at a small map. My favorite guns are typically assault rifles.
