Compass and/or Gyro

We are trying to determine the best way to get a true accurate angular heading of the robot.

2 Years ago we tried using the rate gyro, to some success, but to abrupt of a turn, or a jolt and we would lose our heading. It was however successful enough to help with our autonomous.

I've read of the idea of using a compass to periodically reset the gyro, so here is my question.

How would you determine when it is appropriate to reset the gyro's heading using the compass?

Is it better to do it based on an error percentage between the 2 sensors? or a time based reset period.

Thanks,
- Bochek
