Another option would be to try the 4 wrap system that speer uses. No knots involved and works very well. http://www.imrisk.com/hammock/speerknot.htm
Personally, I didn't much like the rope that came with the Clark. Had I kept mine, I would have replaced that with a system of cords, tree straps and rings. Makes setting up much easier and as mentioned above, no knots to remember!
