Glad you asked. I love this stuff. It's basically 100LB deep sea fishing line but it is not "plastic" like traditional fishing line and is more "fiborous" like extremely thin, wax treated rope. "Fireline" is the brand. So far 100LB is the strongest I have found and I have only found it at Bass Pro Shops so far. This stuff is great. You see in the pic how easy it is to get 50' of it in to a tiny pocket kit. <img src="/images/graemlins/smile.gif" alt="" />
