noob's right. Marathon, on the other hand is much better IMO, so that way people can't run away, or get enough distance to start comfortably aiming, like say, at your feet. Magnums reload fairly quick on their own, and you can't ADS so SoH isn't that useful anyway even pro. I'd recommend swapping Lightweight for either Stopping Power or Hardline. Maybe Cold Blood, but personally I LOVE enemy Harriers when I have a shield. Get yourself in a corner where it can see you, crouch, and just keep the shield pointed at it. It'll usually stay aimed at you the whole time, letting you rack up the points and keeping the rest of your team safe from it. You have effectively stolen their Harrier to benefit YOU in every way. Attack Helis and Pavelows are ok too, but they'll probably give up shooting you after a couple bursts and move on.
