Weight weenie wise, this rotor is lighter than the XTR version and lighter than the Ultegra and Dura-ace versions. This is why I got it. Works well on my road bike paired to Ultegra R8000 shiftercaliper. I'm using 160mm front140mm rear.
What else can I say? It works as intended.
Finally upgraded bike from resin-only to sintered compatible discs. Working well and no squeals in the first couple hundred miles, even in the wet. These look pretty rad, too.
