Getting more into this now the more i play it though still cant decide on my best Class setup combo, any ideas?
Depends on your gametype and how you play. Just experiment with a few perks to unlock pro, try a few more and build a class that suits you.
I will probably end up using either
Hardline Pro to get the choice of a random chance at another killstreak when it gives me ammo or Uav
Sleight pro of hand
Hacker pro to hack the care packages I call in.
or
Ghost Pro
Sleight of hand Pro
Ninja Pro
or for capture the flag
Lightweight
Marathon
Sleight of hand
Have a look at this list of pro perks to see which will suit you best....

I'm changing my set up constantly until I unlock all the pro perks I want. Stuck with the Ak74U though. With red dot.
