Taking away 2 MG FF of A-5 improves zoom, climb and acceleration by some 3 %. A negligible difference, but deceptive...most AH planes are inside 10% difference compared to each other.
Taking away firepower from a plane is risky stuff IMO. It should be done with regard to one's flying style. And you never know how many buffs you'll meet or scissor snapshots you'll get.
