Heres what I think: F2000 is a beastly gun, however, I wouldn't use stopping power for the F2000 or AA-12 since they both have a high rate a fire, so either Lightweight, Cold-blooded, or Danger close (for your nade launcher) would be a better red perk. As for the AA-12, again, a beastly gun, but fmj's with shotgun doesn't penetrate anything except for sheet metal, so either a grip (for a faster switch if your gonna use it as a secondary) or extended mags (for an aggressive role for that gun) would be a better choice. Other than that, sounds like a great class!
