Perk LA7(speed and 3 canons, turns good too), G10(UFO climb and speed), D9(speed and acceleration), N1k1(turn and 4 canons).
Don't perk P51D, I know it's fast but it was available in great numbers and doesn't carry any pingpingcrack canons.
Don't perk typhy, even if it has devastative canons and ubber speed, it's stall characteristiques make it useless to the comon turnfighter.
Perk the D30? heuuu ... Half of the planeset outrun it, the other half outturn it, some do both... all outaccelerate it and outclimb it. I think you want it perked because of it's load out. I don't think it's necessary, the pilot who goes hvy pays the price ... it's like a 25k B17 mission, it takes you for ever to reach 13k and you have to jettision everything if u encounter a single fighter between your base and the target.
