Hi folks, I am just getting into trolling with leadcore line. I haven;t a clue as to how to attach it to Power Pro baking and/or mono. I have 300 yards of PP and I want to attach 10 colors of lead. I've tried the Willis Knot - it's impossible to get it! the PP is too LIMP to be threaded throught he sheathing. Is there another knot that will securely connect the various lines? thanks a lot in advance! NK
