Way back before I discovered my love affair with the 190, I flew the PonyD almost exclusively. I won't claim to be an expert, though more familiar than any noob.
I was of the opinion that the PonyD, 6-guns and down to 25% fuel - flown in the vertical - was good enough to fight anything. I had plenty of kills down on the deck stall fighting. As Dave notes, most other sticks expect the Pony to flash by and run. Hard aggressive turns cause most of them to make bad decisions. Actually, since they expect you to run-Stang they keep their "E" as high as possible and your aggressive turn (bleeding "E") gets them to overshoot most of the time. Then....close in for the kill and don't miss your shots.
