Great all purpose attractor pattern. The Tungsten Rainbow Czech Nymph can be fished with Czech Nymphing techiniques, but it is equally effective fished with an indicator rig. The Rainbow Czech nymph is a particularly good patten on tailwaters, where it doubles as an attractor nymph or a scud pattern. Fish it as a team with another nymph in a euro rig, or fish it as the lead fly in a two fly indicator nymph rig.
