The main strengths of the Devaux JBNT35 Tungsten Nymph lie in their ability to faithfully mimic the silhouette and behavior of natural prey. Thanks to their tungsten weighting, you can effectively fish all water columns, which is essential for targeting fish at varying depths. The robust hook ensures excellent hook-hold, reducing losses even during fights with larger specimens. The perfectly shaped bend combined with flexible fibers creates an attractive movement that triggers strikes. Additionally, the solid construction increases fly longevity for regular use throughout the season.

To maximize results with the JBNT35, use a fine, discreet leader to favor a natural presentation of the nymph. Ideal use is in underhand dead-drift or indicator nymphing to take full advantage of the weighting. The pattern is well suited to fast, deep fishing but remains effective in slower water. For added stealth, use a fluorocarbon tippet in clear water. Finally, the JBNT35 performs exceptionally well paired with a small dry fly or in sight-nymphing to entice wary fish.
