Know what I'd love? An A-6A Intruder. A -B model as well!
Speeding along at 200 feet, 500-lb bombs under the wings (or Shrikes, if you fly the B!), yes please!
I voted for the F-16, though. As much as BMS has done a good job of making Falcon 4 a modern(ish) sim, it's nowhere near DCS, and I have loved the Viper ever since I watched Iron Eagle as a kid!
