Good question. I believe I only used it on a 10' 4wt rod in the 2012 Rocky Mountain Summer season, couple times a week max when I was in Denver on a short term contract. I'm a 4wt and 6wt Winston guy myself so the WF5 line was only useful to me to over-line the 4wt for indicator nymphing. And the rod I had it on exploded in my face Labor Day weekend 2012 which was the last time that line got wet.

Its got the factory loops on both ends. Does that help at all?
