Look up AMSteel blue. Great stuff. Many have changed form steel cable to this stuff for winching and the type of work you are doing. I just bought some 1/8" diameter stuff for some things I have going on at less than a quater a foot from Redden Marine. 1/8" diameter has a 2300 lb tensile strength. Use the coupon code hammockforum. The stuff is made by Samson and you can go to their website to find the weight rating you desire. They even have whipping instructions available so you can make nice clean looped ends and things like that.
