I think your categories are too narrow and simplistic. How many of you film your fights? I like to film mine, let me explain how my average sortie tends to play out in terms of stages:
1) I locate a nice fight on the map, up for the fight from a nearby field almost always with 100% fuel and DT's. I tailor my style to my diminishing fuel load as the flight progresses.
2) I then Gain altitude to be at or slightly above 75% of the reported/guesstimated enemy within optimal aircraft performance limits, which is generally 15k or less.
3) Usually I overfly the focal point of the fight scanning for targets at or above my altitude. Once those are dead, flee or are dragged down I continue to the opposite perimiter of the fight area.
4) Once on the extreme edge of the fight opposite the side my home field is on I vector toward friendly territory engaging targets of opportunity along the way, always highest to lowest and fastest to slowest if in an E Fighter or the most nimble first if in a turn fighter, engaging and destroying cons all the way down to deck if necessary.
5) Once my altitude/energy degrades to the point I am either on the deck or on the bottom of the pile I attempt to gain seperation and egress toward my field and friendlies in order to regain operational altitude.
6) Repeat stages 2-5
Now, perhaps at the beginning of the sortie or after stage 6 I am BnZ'ing, especially if there are no enemy cons at or above my altitude and my fuel load is very heavy. By stage 4 I am likely E fighting cons at any altitude, at/above/below. Between stages 4 and 5 I am likely TnBing close to or on the deck, dodging BnZers and E fighters before I attempt to gain seperation and disengage to regain my energy state composure...
So, was I furballing, dogfighting, E fighting, BnZing, seal clubbing, fighting at an advantage or fighting at a disadvantage? The answer is almost certainly all of the above...
I would even go so far as to say, anyone who can categorize their fighting style as stricly type a or b is either lying, dellusional or so hopelessly one dimensional in their approach to air combat they aren't enjoying nearly the fun or the effectiveness they could be if they adopted a more versatile and adaptive style..
