So I prestiged a few nights ago. Had 4 tokens, and 6 hrs of double xp. I unlocked MP7, FAD, and Dead Silence for all my prestiges, and was able to go from lvl 1 to about 60 with the 6 hours of double xp. During that time I used the FAD and MP7 the whole time. Lately I used the MP7 with FMG9 Akimbo after I saw people using it. I used this set up:

MP7 - Two Attachments: Suppressor + Rapid Fire
FMG9 - Akimbo
Frag Grenades
Flash Grenades

Extreme Conditioning Pro
QuickDraw Pro
Dead Silence Pro

Martydom

With this setup I went about 45-6. Every time I spawned I'd be able to run right over to their side and gun down their whole team. It was on Mission. I ran around in circles in the upper middle area and I was killing guys left and right. Both guns are hip spreaying monsters. Has anyone else done this or used anything like this? Comments? If you like the sound of this setup, do take it, I have no care. In fact its fast, deadly, and silent. ;)
