We used the 8" VexPro Mecanum wheels this season with 1/2" round keyed VersaHubs and were pleased with them. Our robot only competed in 1 regional event but we never had to use any of our spare wheels or rollers. Our students loved not having to spend hours assembling them like last season and I loved the multi-pound weight savings we got in our drivetrain by switching.

And for reference, they just barely fit on the Andymark Nanotube output shafts for direct drive (I don't think we had to get the longer shafts, but that was a while ago).
