I built my own tether out of climbing rope. I went and visited Back Country North in my home town this past spring I started with a 10' piece of rope. After about a month of working with my saddle and rope tether I have it down to a 5'5" piece of rope with its perfect for large and small trees. I like that i don't have to have the rope right at head leave with means it out of my way for either bow or rifle hunting.
