Try using the KH2002 with the cobra scope.see how fast you can move while aiming vs other guns with scopes. (it only works on the KH2002 and the F2000 as far as i can tell)
Edit:i learned some cool tricks from this guy http://www.youtube.com/user/rivaLxfactor/feed
Didn't even know you can disable a tank with a single rocket.
