I use Thrustmaster's TARGET software, which also works with the Cougar HOTAS and the TM16000 joystick. I don't know if TARGET works with your system.
I find aiming very difficult at times when doing hard maneuvres (who doesn't?) and trying to keep the reticle centered while my head seems to be bobbing around. If you have one joystick button assigned for pausing/unpausing TrackIR and another button for centering TrackIR, that may work for you after a little practice.
