AH fights are exactly how my fights at Air Combat USA went -- where the guys were about equal, they ended up in stallfights on the "deck", not rolling scissors.
That falls into the 90% of fights being realistic I was talking about earlier. But with sticks at a certain level, Batfink for instance you will ALWAYS run into what I'm talking about. If you fly well enough to actually wind up on their tail in the first place during an equal duel, they will use a pullup in combination with killing energy, followed by a hammerhead rotation. They WILL get a shot coming back down. Hit or miss, you will end up on the defensive unless you can also pull up and begin utilizing the same sort of maneuvers. The fight will hinge on snapshots taken as you exchange positions in this hammerhead series, and as I say, in my observation this is where almost every duel between high-level pilots eventually goes.
One also runs into some pilots who aren't particularly great at anything but these sort of maneuvers, indicating that god-level flying ability isn't required to use the FM in this way.
One incident of this sort I remember is being 200 yards behind and slightly to the right of a Corsair, both of us being very low and slow, while flying an FM2. Both of us were level turning by this point. The Corsair rotates while very near flat almost 180 degrees to the right to face me, does not shoot me in the face in the spirit of good sportsmanship I suppose, flies under me, and the fight continues
