Liable to change, but here's what i use so far:
Famas Silencer (and red dot with warlord (Green 3 Dots on Blue Lens)) with Tiger Camo
I have a secondary? Wonder what it is...
Semtex
The Yellow Poison Gas thingamabob
Camera Spike (probably gonna switch to motion sensor later when I have spare cash)
Scavenger Pro
Sleight of Hand (or Warlord (pro's ready but not bought yet))
Ninja
I LOVE the Freakin' 2000!!

Wish-list for Modern warfare 3:
Freakin' 2000
Desert Eagle Tac-Knife
Single 1887
Cod4 Red Tiger Camo
Blue version of Cod4 Red Tiger Camo
MW2 "powerful secondary" system
Then Standard stuff like:
M4, Ak-47, Scar-H, Silencers, Urban Camo, a sniper that performs like the Wa and looks like the EBR, Bling Pro, Cold-Blooded Pro, Ninja Pro, and that kinda stuff they'll probably put in anyway.
