I've actually switched from primarily running Ghost and have lately been running Hardline Pro w/ the Counter Spy Plane. I still will get screwed on occasion when my Counter isn't up though, as I'm a heavy flanker.
Thats something I never thought of ...... I almost always use a silencer.
Although I prefer killstreaks rewards that kill people. ........... even when I switch off for team matches, I'd prefer to go with sp/heli/bb over using a ksr for stealth.
I prefer my KSRs to kill as well, however, even when using Ghost and a silencer, a CSP is a nice thing to save several of for when and if the enemy brings in a SR-71. I'll end a game with 3 or 4 that I never even used.
