Dogfighting with TrackIR and an X52 Pro HOTAS combo is the dog's bollox, imho. I've had my TrackIR for years, and it's so good to see it supported in ED. It really does give you an advantage. You can follow that interdiction escape vector much more easily (because you rarely lose sight of it completely), and being able to keep an enemy in sight - even through the roof windscreen, if you have one - makes all the difference when it comes to predicting his movements. Definitely recommended.
