The Willis Knot is easy to tie. I just read a tip to eliminate the end of the Dacron from fraying; after removing the lead, insert a large needle/safety pin and heat the Dacron to fuse the material thus eliminating the fraying.
Mark was telling me he was going to be be called Slipknot II. Don't worry about Mark. He can fish with the best of them, and for the record, I know Craig can too.
