The rings came in today so I put them on the crank. I must say, this crankset is easily the nicest single piece of bike schwag I've ever spent my money on. The machine work is incredible and it just looks plain snazzy! I wish I had a scale to see how much it weighs with the chainrings, but it feels just as light if not lighter than my SRAM Red compact crank. It's a very impressive piece for sure.

Btw, I didn't secure the chainring bolts down to their 7-8 Nm spec because I ran into a little problem. The rear of the chainring bolts appear to use some kind of Torx wrench to hold them in place while the front is torqued with a standard 5mm Allen. I used a "T40" sized Torx (close in size to a 6mm Allen and the largest size I have), but it seemed like a loose fit. I didn't want to risk stripping out the back of the chainring bolts so they are only thumb-tight right now. A 6mm Allen/hex seemed to fit too, but it also seemed a bit loose. Anyone know what I'm supposed to use to keep these stupid things from spinning while I torque them down?
