As with so many things, it's important to understand how much noise and drift you can accept. If you're only using the gyro for autonomous (15 seconds long) or to do short-term maneuvers (like backing up in a straight line without your probe knocking down a stack), you can allow significantly more drift than if you're expecting your "arena coordinates" mecanum drive to be stable through a full 2-1/2 minute match. If you're looking for full-match alignment and can't get it from your gyro or encoders, consider if your strategy puts you up against a wall or other well-defined feature of the field on a regular basis, and see if you can use that as an opportunity for a heading correction.
