May I suggest that you try it under the hood? I've found that it makes
flying my airplane no-gyro very easy. That may not be true of higher
performance airplanes, I haven't tried it in one.

This information is very valuable as a cross-check to the flight
instruments.

Agreed, but I don't think I'm a good enough pilot to use it safely in
a partial-panel situation, where I'm already under a great deal of
stress.

Try it. I think you'll find it reduces the stress.
