Usage tips and recommended rigs:
To fully exploit the potential of the JBNT04 Tungsten Nymph Fly, adjust your tippet diameter according to current and water clarity. Using a fine, flowing leader head or a short rig for French nymphing enhances presentation and nymph responsiveness. This fly excels both in natural drift, in "touch" fishing, or with slight animation to provoke a strike. Make a precise cast, allow the nymph to sink, then follow the line slowly to detect the faintest takes.
