In past years when we needed high accuracy during turns and/or expect collisions or other sources of wheel slip or orientation change, we put the encoders on non-driven follower wheels. We put the wheels in line with the drive wheel, usually on a swing-arm and spring loaded them to keep in contact with the floor. The VEX omni wheels work great for this. In fact, doing it this way allowed us to remove the gyro, which was nice.
