So far a good, very durable rope
This rope holds up very well. I've read what others have said about the sheath being lousy, but that hasn't been my experience; still no fuzz. I've also taken some long pendulum type falls where the sheath has been dragged across the granite in a manner which would expose the core on a lesser cord, but my Zephyr has survived without any damage that I can't live with. There is no doubt that this rope is heavy (I have the 60m) but for my uses the extra durability and strength of a 10.3 more than compensate.
