JoePA, Bulldog1 here, the one main advantage a string loop gives me when I hunt, I can let down if I have to without the arrow leaving the string. Also if set up right, it keeps the string a little squarer in the nock, adds a little more speed, and takes out what release torque I may have. I would'nt bowhunt without one, just get one that's knotless. Bulldog1
