In reply to UKC Gear:
On the face of it nothing described seems an improvement over the standard choice Mammut Genesis - which has been around for 10-15 years - and the DMM is heavier. (100g might not be much to the reviewer in the alps but it's a lot at the end of a long trad pitch - 3 or 4 lightweight quickdraws, and I have fallen off routes before because of rope weight.)
It's really disappointing if there is still no half rope out there with Genesis durability (and stretch) but ~8mm thick and a lot lighter. Singles have come on hugely in that time period.
