Ya, there is one problem w the ring/bungie system ... w/ a continueous system you only need to take one line out w/ you on the wire as you can work both the main and traveler from the same line just by changing where you grasp it. Once you use the ring/bungie system you will need to take both the main and traveller lines out w/ you
