Does anyone have experience with, or know of some good lightweight (lighter) options to replace the etap chainrings?

Caution: Rotor Qarbon chainrings are 5mm thick and won’t work with non-removable spider hidden-bolt Red cranksets.

Extralite work fine. I'm using 52/36.

What kind of weight savings are we talking? And how is shifting?

Edit: about 60 grams savings with 50/34. 153g vs 93g

My setup on that bike is with 165mm Red carbon Quarq arms (GXP), and a Power2Max NGeco PM Spider (110bcd).
Shifting is great, maybe a little slower than yaw rings, but not terrible. Had some outside chain drop issues, but I sorted that by fixing my BB spacer situation.
Total weight: 687g

Compare that to:
SRAM Red 22 Carbon Exogram, 165mm, GXP, 53/39 Yaw rings: 608g
SRAM Red 22 Carbon Exogram, 165mm, BB30, 50/34 Yaw rings: 520g
SRAM Force 22 Carbon, 165mm, GXP, 53/39 Yaw rings: 715g

(Sorry, I don't have the individual weights for the Yaw rings, but I figure you can goole that easily.)
