For Cn'D:
P90 + Rapid Fire + Silencer.
USP.45 + Akimbo + Silencer.
Bling Pro.
Cold-Blooded Pro.
Ninja Pro.
I'm a sucker for style, and this set up seems to kill quickly enough.
And in TDM, Mini-Uzi + Extended mags; they need more love, I'm tired of UMP45's; I don't like how they fire and I generally don't like the people usin' 'em.
