On the whole, the Sterling Evolution Duetto ropes have performed beautifully; they’ve lived up to their reputation, and I would have to really dig deep to come up with more gripes than the two minor ones listed above. Half ropes are wonderful in general, and these are better than most. Though it seems like a minor point, I thought that it spoke to the rope’s handling that it was so easy to slide clove hitches when adjusting a tie-in, as well as untie knots that had tightened during a fall.
For anyone considering making the jump from singles to halves, these are a solid option—even if you never thought you’d consider switching rope brands again.
