refers to it as the Twist Knot; he also lists others that have gone out of

fashion for fishing, such as the Water Knot, Bowline, Jam Knot, Double
Jam, Tiller Hitch, Stevedore Knot, and Figure Eight Knot. Knots come
and go.

Cortland’s best-selling freshwater fly line, the Classic 444 weight-forward line. Use loop-to-loop
connections to attach the fly line to the braided backing and the leader butt.

Cortland’s Big Fly line has welded loops at both ends, which makes rigging quick and easy—
simply tie loops on the backing and leader butt and attach the fly line with loop-to-loop
connections.

I’ll spare you any tutorial on the way things used to be when it came to
measuring line thickness with a micrometer to assemble lines and the
leader; instead, let’s look at how things are today. As I mentioned earlier,
fly lines are now rated by number, lowest for light tackle (0- to 5-weight)
to middleweights (5- to 9-weight) to heavier weights (from 10- to 12-
weight or so), and then some outliers such as 13- or 14-weights for big-
game ocean species such as sailfish, marlin, tuna, sharks, and the like.
