I have dog fighted in all of them too Bozon. F3 can do nothing to increase rate of climb, acceleration, ability to roll and turn, agility, to dive....ect. Of them all the A20 probably has the most worth but tell me, how many times do you see A20s upp to dog fight when FHs are still up? I would argue F3 doesnt even give you much more SA cause you still have to work buttons on your rig instead of just turning your head natural with a Track IR.
They are all last ditch suicide machines desperate to find and HO a goon before they themselves get clobbered. Add the TU2 to it. Try rolling that banana or pulling it out of a dive.
