Usage tips and recommended rigs:
To fully exploit the potential of the Devaux Gammarus JBG04, favor a thin, discreet leader to optimize natural drift. It is ideally used as a subsurface fly, in sight nymphing, or in tandem with a heavier nymph to prospect different depths quickly. Pairing with a light beadhead or a relaxed presentation on a bare hook maximizes realism. This fly excels in clear rivers as well as in more stained waters, especially during periods when gammarus are active.
