i've been running:

Type 95 w/ RDS and rapid fire
frag
stun

SoH Pro
Assassin Pro
Stalker Pro

support streak because i die too much w/ UAV, CUAV and Stealth Bomber. Sometimes ill just run UAV and CUAV and just constantly spam them the entire match.

type 95 is such a sick sick gun. 2 shot kills FTW! I like the PP90 whatever for smaller maps sometimes also. After i've got to know the maps better i like alot of them. Carbon is the AIDS, but everything else is terrible. Big fan of Fallen now and i hated it the first few times i played it.
