We decided against a flywheel, because we found that the mass slowed our ability to get back up to speed after a shot. Instead we use a tightly-controlled PID loop with 'normal' speed at about 70% power. The extra 30% "headroom" allows up to spool the wheel back to speed in about 1.6 seconds at present, but we are working to improve the response time.

One difference to your wheel is that we use two powered wheels opposing each other, allowing us to more closely control backspin.
