consider another hybrid solution with coarse and fine scaled gyros. Coarse is a high-max-rate-low-resolution gyro and the fine is a low-max-rate-high resolution gyro. Simply switch the heading integrator input from the fine gryo to the coarse when saturation is detected on the fine gyro. This is added complexity, but gives you the best of both worlds of precision and dynamic range.

I would use the encoder heading over this if they are on the robot.....if not , this might prove cost effective.
What about using a compass. Wouldn't this give absolute position, without the need for gyros? Sure, they're a little more expensive, but their accuracy would be much more than that of a gyroscope.
