Not sure about the 0.60 OC but the prototype I have certainly is more efficient to me.
Tried the OC with the Darwin today and I still don't love the Darwin handle even though it's a pretty good match for the WR3 in the absence of a handle designed for it. Not the most secure grip with wet fingers. Prefer the WRH7 actually.
I did get some blade feel this time, maybe the blade wasn't lined up correctly. The shave result was the same as the first try of the OC but that time I barely felt the blade somehow? Still no irritation after the shave.
