**I think we began using this loop-to-loop system in the 1960s and quickly determined that a single loop could mean a lost fish, especially with a jumping one. When we used a surgeon's knot to make a double loop connection, we eliminated the problem. I think your friends are giving you good advice. However, if you are using gelspun backing, I would suggest you do what the Australians do - pass the backing loop through the fly-line loop, then over the entire fly line like normal, but then twist the loop and pass it over the reel, then repeat. Unlike Dacron loops, a gelspun loop tends to loosen from the fly line during a fight and can result in a weak girth hitch. When the method practiced Down Under is used, the gelspun forms a braid when pulled and remains in position.
