Trouble is, bad knots may fail, so you'll eventually have to pay some attention to them. But the choices can be bewildering. A few self-proclaimed experts have a queer eye for knots, weaving elaborate webs like so many spiders with results that might work for them but are pure Greek to anyone else. Tackle companies are also on the bandwagon, promoting themselves with variations like the Trilene knot, the Rapala knot, the Orvis knot, and so on. While some are worthwhile, the proliferation of styles has gotten a little silly. I've often thought of adding one new twist to an old-time perfection loop, for example, and promoting it as the Merwin knot all over the Internet. Pretty dumb, you say? Exactly.
