The best I have found for both weight and strength is using the Sullivan 2-56 eye screw and nylon coated Kevlar. The Kevlar is sold by an outfit in Ca called Aerospace Composites Products. I use 1/8" K&S aluminum tube cut into 3/8" sections as the crimp. Crimp add a drop of medium CA and then heat shrink. Bullet proof, light and won't stretch.
