Trust me, they're worth it. And you'll never have to replace them due to wear!

You may have seen these wheels on frisbee shooters in 2013; I think 341, 2056, 1114, 254, among others all had them. 2056 used one as a shooter wheel in 2012 as well. They're pretty nice. The only catch is you have to make a hub for them, though I've heard you can make a Vex VersaHub work in a pinch.

You'll want PN 2477K36. We used 60A durometer.

I'm curious as to the difference between these and the ones similar to what we used (McMaster 87235K79). From a cost comparison at same width wheels you are talking ~$8.30/wheel vs ~$30/wheel. For our collector we used the 40A.
