Here's what I'm currently using. Again, keep in mind that it's pretty specific to the distance you sit back from the TIR unit so it may require adjustments to your specific preferences but it's a good template to work off of if it doesn't suit you out of the box.
Save it as an .xml file (create notepad doc then copy/paste this in there and rename file to CharveL.xml) in your "program files (x86)\NaturalPoint\TrackIR5\Profiles
