As an alternate sensor, one might consider the US Digital MA3, which has a much smaller dead band (it is pretty minuscule.) They are a little more expensive, though, at around $40+. However, you can get a ball-bearing version that can sustain higher rotational speeds.

This is what we like to use for certain things on 461. I found out about them when asking some folks on 469 about their swerve drive a few years back.

I guess my method of dealing with dead bands is avoiding them entirely if possible!
