The major advantage of the Devaux JBNT27-N tungsten nymph lies in its ability to combine striking realism with unparalleled fishing efficiency. Its silhouette, life-like movement in the water and the subtle shine of tungsten attract attention from river predators while remaining discreet to the most educated fish. Using tungsten is a real asset because it allows the fly to reach the desired water layer quickly and hold its position without unnatural drift.

Thanks to its legendary versatility, the JBNT27-N is suitable for tight-line nymphing as well as indicator or drift techniques, and remains effective in current seams, deep pools or fast runs. It is also used to prospect edges or obstacle zones where alert trout lie in wait. The optimized tying promotes flawless presentation and immediate hook sets.

Recommended use and rigging:
To fully benefit from the effectiveness of the Devaux JBNT27-N nymph, it is recommended to fish it on a fine tippet, paired with a subtle leader to optimize discretion while fishing. A light, fast-action rod will allow you to animate the fly more convincingly and feel the slightest strike. Combine, for example, with a fluorocarbon tippet for extra stealth and strength. In tight-line nymphing, the JBNT27-N excels for its rapid sinking and stability during drifts. It also gives very good results with alternating retrieves or fished in tandem, coupled with another lighter nymph on the dropper.

Its tungsten weighting really makes the difference, especially in powerful currents. It sinks fast, sits naturally and the strikes are solid. It has become my go-to on demanding beats and technical water!”
