Re: Recommended gyros that can keep up with fast rotation?

This is true. However, with good calibration, you can get the drift down to ~2-3 degrees over the course of a match.

That's likely enough to snap to a rough position - and if you want to use that for shooting, you'll need either vision or manual alignment anyways, so not being exactly exact isn't a problem.
