I just got UCCE this week, and it has been so long since I played BCMG, that I had completely forgotten about the benefits of the Logitech Profiler. Thanks for posting this topic.
One related tip that I have found quite useful: When programming buttons for commands, such as ctrl+s, make sure that the profiler is set to record pauses. Otherwise, you get "s" in-game instead of 'ctrl+s" about half the time. I like to use the "side" buttons on my Extreme 3D Pro for Tacops, Tactical, Perscan, Docking, etc.
As far as the roll/yaw axes are concerned, I have not re-learned enough yet to have much of a preference. I am still "owned" by the AI fighter pilots either way.
