Dura ace rings, no question. Dura ace chainrings are much stiffer than Srams offering and with di2 it will result in much better shifts.

It's also a benefit that all their chainring sizes are 110bcd, so you can go from compact (50-34) to standard (53/39) without having to buy a new spider. Sram you are limited to compact/mid compact or standard.

I'm running DFour with 9000 rings. The DA 9000 large ring is 30 grams lighter than Sram Red large ring when you also factor in that the DA ring also has four nuts already built-in. I also like the looks of the DFour. I also chose the BB30 version of the DFour. If your frame can support BB30 I'd recommend it.
