DUDE! Awesome link with a shit-ton of good info. Glad that they really did split Ghost up into two categories but it sucks that they are in different slots so people can be completely invisible from everything.
Right now my favorite perk setup would be Quick Draw (faster aiming/recover from throwing grenades faster) Sleight of Hand (faster reload, faster weapon swap) and Sit Rep (detect enemy equipment and louder enemy footsteps)
I just prey that Sit Rep Pro is a lot easier to get in this game than it was in MW2. The only way I could get the Pro version of Sit Rep would be to find a guy who was using Scavenger with claymores then I would destroy his claymores and walk right up to the dude and let him kill me so he could get another claymore to put down.
You had to destroy 120 ****ing claymores to get the Pro version in MW2.
