agreed, get the title packages. once you stop prestiging its the only thing of value you'll find in the shop

i would say c4 or a perk

Double XP, if you already have all the packages.

Yeah the titles. Once you have all classes, just get the miles and titles as they are pretty cool, but not worth it when you still need classes. I'm going to stop where I am at 6th, with 8 classes and all unlocked title packs, but I can still prestige in Call of Duty 4 and Modern Warfare 2 to get those other 2 classes.

Unlock Overkill. Then rock out with the MP7 as your 1st primary and the ACR as your second. The MP7 works great for the close-mid range stuff, and the ACR handles the long range.With overkill, you'll only get one attachment on your second primary, but the beauty of the ACR is that the iron sights are so good you don't need a red dot or a scope, so you can go with a silencer to eliminate the kick.

I love that combo paired with pro'd SOH and stalker

Keep your powder dry,
