I ordered an auto wind fly reel for my pull up rope. I know someone said they used one here. Problem is it wont feed out 20' w/o the spring getting too tight. I put it on my fly rod and put a hand crank reel on my bag for my bow rope. I like the fly line as it is stiff enough so it doesn't blow around and catch on twigs. really light wt and quiet. I had an HSS ribbon reel and it caught on every small twig in the area of my tree.
