We have a gyro reset button, and I end up calibrating the gyro many times in match. Even with the reset, I sometimes find myself driving with 25+ degrees of error.
Somebody above said that this was impossibly disorienting, but I find it manageable.
I got used to gyro inaccuracies after some practice.

Nevertheless, we're determined to improve the system. We are going to try using two gyros, one mounted upside down. 1717 does this and says it helps a lot.

Even if I had to deal with gyro drift forever, if still greatly prefer field centric over robot centric

I don't think you need two gyros or non-kit gyros. We have seen similar problems with the WPI gyro code, which is why we do our own bias calculation and integration - see my above post. If you need more details, let me know.
