Sling idea for fine tuning

After working with both the previous medium treb and the mini-trebs i came to the conlcusion that there had to be a better way to adjust the sling length. The idea I came up with came from a friendship bracelet that my son brought home. I used this link: http://www.animatedknots.com/index.php?LogoImage=LogoGrog.jpg&Website=www.animatedknots.com and used the double fishermans knot. The site is a great site to learn about knots, many different knots, at least 50. I then used a wire rope clamp to secure the rope at the desired length. The clamps that I used were too big but I found smaller ones and I hope they work better. Good luck!
