Thanks guys, it didn't take me too long to get used to TrackIR, probably around a week of flying and I was comfortable with it. Just don't get discouraged if you have trouble getting used to it at first, and fiddle around with the response curves for the 6 degrees of motion, really helps. As you get better, you can increase the sensitivity.
Yeah music choice is tough, not everyone's going to "feel it" - heh.
