I guess that's why many are using HALL switches instead of VRS; they really 
can cope with a zero speed tooth. And the capacity to get a nice square 
output makes them very easy to use.
Sadly the hall switch that I'm playing with is VERY insensitive, so it 
requires a mega magnet to trigger it, and I've been unable to use it as a 
tooth sensor.... :(
So I guess a differential hall switch IS required after all if you want to use 
it as a CPS.
