That's the one. If you look closely at the current world champion's robot, team 1477, that's the wheel they used.

I saw them use it on their practice bot just before Championships. After shooting 50 or so disks, it showed no signs of use. They even had to tune their banebots back to 50%. It provided a lot of grip and a consistent shooting platform.
