I recently carried the RAD for a 4 night hut to hut trip in the Silvretta Alps.
Once you get over how thin and light the RAD is, then you can really appreciate how light and compact it is in your pack.
Typical for a ski touring trip, we never actually had to use the RAD line. But, I was confident that if we needed to it would perform well.
There were 4 in our group, so we also carried a more standard 8mm glacier rope. We took this out of the pack for a short abseil, but I think the RAD would also have done fine. Having 1 normal 8mm glacier rope and 1 RAD line in a party would be a good strategy.
