This would be why I was questioning if steller was switching from hex bearings to plain round bearings. I knew hex bearings were not equivalent to round in some ways, though I didn't know the specifics.

And so much this. My team was claiming we were out of thunderhex bearings, so they swapped in some "normal" hex bearings. I informed them that the hex bore bearings were only for use as a last resort, and week 2 was not last resort time. Thunder hex just makes life easier. The real problem is that Versaplanetary outputs only come in true hex, not thunder hex. So i have to turn them down for any high speed applications.
