I've since become very cautious about gyros and how we use them. This was with the KOP gyro and WPILib Gyro class. That lead to us to use ADXRS453, and we have been very pleased since with it's performance.
Sorry I'm a little late to the party on this thread. As far as this gyro goes (ADXRS453), it looks like there are two packaging options (ADXRS453BEYZ and ADXRS453BRGZ), I'm wondering which one you would recommend, and how you interface with it.

Thanks in advance.
