Its interesting. 90% of my sorties are in a brewster. The planes I meet in battle are spit 16s and 190s. 51s rarely want to play. Lose alot. BUT killing a spit 16 is just so sweet...
Maybe you would get some more attention other than pickers if you chose a different ride. The Uber Brewster isn't going to get you much for commitment from enemy unless it's another Brewster, ki43, or a6m. It's basically a helicopter that will best 99% of the plane set in a drag out low speed fight.
I'll take 1 or 2 turns with a Brewster in something like a 38 or 51, and sticking around longer than that is suicide.
Fm2, 109f4, spit9, and similar planes that can turn well, just not helicopters, will probably boost the amount someone decides to engage you and stick with it.
