Beings it's my 1st pair of Urethane wheels... it's quite the upgrade from the plastic and Polyurethane ones. The bearings seem better than the CNC Poly wheels. But maybe that's a "me thing". I love the slight bit more grip level these carry compared to the CNCs. I feel like maybe the 65D area truly is the "sweet spot" without ever trying them. But, I wanted to step into that before going from one potential extreme to another. So far tho, I'm quite pleased with them and look forward to testing them out more and comparing them to the other wheels I've grown to know a bit better.
