Hyperclimb is the only rope I have ever owned. My experience is that it flattens out when I use a top anchor with a butterfly/Quickie or when I ran it over the 1" construction rods in my warehouse.
It runs well on the Rope Runner Pro set around 3+. Also smooth with a Rope Wrench and
Michuacan with 8 mm Ocean.
Today I finally milked the two ropes I have. Each is 200 feet. The purple had been climbed on a little. The orange none at all. The purple milked out about 45 inches past the core on the first pass. The orange was considerably less. So I probably should spend more time on the orange. I made three passes with each. Some photos of results just in case it means something to anyone. Will post when I climb on it again if I notice a difference, which I expect is likely. Already feels smoother. Maybe won't get my top anchor stuck due to friction again.
EDIT: Total milked from purple, which had been climbed on a few times, = 65" for 200'. Total for orange that had not been climbed on = 32". Not sure if climbing made all the difference or if the sheaths were tightened differently during production.
Hyperclimb Purple, 200' First Pass = ~45" past core.
Hyperclimb Purple, 200' Second Pass = ~12" past core.
Hyperclimb Purple, 200' Third Pass = ~5" past core.
Hyperclimb Orange (virgin, never climbed), 200' First Pass = ~20" past core.
Hyperclimb Orange (virgin, never climbed), 200' Second Pass = another 8" past core.
Photo didn't come out, but on the third pass it added another 4" or so past the core.
