Instead, fly-fishers cast a fly line, which is heavy and thick, like cord. It's covered with plastic so that it floats and glides through the rod guides. A 9-foot piece of clear fishing line called a leader connects the fly to the line. The leader is less visible to fish than the fly line. And because it's lighter, it splashes less on the water.
Flies are too light to cast with spinning tackle.
Most fly rods are longer and more flexible than spinning rods. The fly rod must bend enough to fling the heavy fly line forward. Its main purpose is to store extra line. Begin practicing on an open grassy area. Instead of a fly, tie a small piece of yarn to your leader.
