I can't believe it, but the 190a5 is rapidly becoming my favorite plane in the game.
It feels so nimble, and doesn't have the elevator problems of the 109 at high speed. Tons of cannon rounds so you can spray em out there on low percentage shots.
The roll, though, is what has me sold. You can change direction instantaneously. I don't know that I've mastered that at all, but I definately miss it when I don't have it.
Try as I might, I really don't fly the 109 well. I can hang in it, but against anyone who knows what they're doing I'm gonna be toast.
