However, We're interested in trying ThunderHex. I like the beefy bearing support, and I also like the thru-hole since that would make life exceptionally easy for a few things in a WCD setup (#10 thru-bolt that acts as encoder attachment).
I have had experiences with plastic hubs and a steel square shaft before - the plastic eventually fatigues and rounds out. Is this an issue with the ThunderHex + Colson combo? It wouldn't necessary mean I don't use either, but I'd like to know if using them in combination for a potentially torque-heavy game is a bad idea over the course of a competition.
Edit - also useful to know for things like conveyors & wheeled shooters, which may see spikes in torque due to jamming/etc.

3476 switched over to thunderhex. I highly recommend it. We still have our inventory of 1/2" hex because its pretty easy to use a lathe to convert to thunderhex.
As for high torque, we have the colson+ thunderhex combo on our 2013 robot now and we will see how well it does when we compete with it in China. I will let you know how it goes but I am confident it will be fine.
