Hello to all I was just getting ready to splice up a friction saver and was wondering exactly how big I should make. I would like to be able to use it to work a spar using a prussik to adjust. As well as use it in place of my rope guide from time to time on nasty trees or when working for someone else so i don't damage my higher dollar equipment working for someone who won't pay accordingly. Suggestions on lenghts would be great thanks.
