We just added these to the site. We found the UCR works really well as an adjustable ridgeline because the extra slack winds up close to the ends of the hammock and out of the way. We also ore offering a version that is disconnectable with a titanium ridge line biner so you can lounge without being scalped. The bury is followed up by a prussic so it locks the bury in place. (Thank you Stg Rock) They are made out of Dynaglide so they are very strong and durable. Nothing but the best for you guys.
