Hang, yep.
I landed a ten kill in the 51D recently and since that was unusual for me
I decided I'd actually check to see how many perks that earned me.
I got 8.something for killing some nik, la, spit, fw and -109 types.
So, I could have earned _almost_ two rides in the -51D with a mixed 10 kill A2A sortie.
The whole perk idea... phhhttt.
Fly what you like. Like what you fly. Don't worry about what the other guy flies.
Want to limit "ubers"? Give everybody ONE of each uber at the start of a tour. Use it or not. Rearming allowed. Crash, die, land, whatever, you're done for the tour.
How do yas like that one?
I STILL wouldn't fly perkies.
