Usage tips and recommended rigs

To exploit the full potential of the JBE49 emergent flies, use a thin leader, ideally fluorocarbon, for maximum discretion. Prefer a long-tipped rig to allow a free, natural drift. Alternate it with nymphs if fish refuse the emergents on the surface. Ideal on slow to medium-fast rivers, these flies are also highly effective in reservoirs during hatches, where fish closely inspect prey. Adapt your casting technique to distance and fish holding zones to maximize visibility and attractiveness of the fly. To prolong buoyancy, apply a little floatant to the thorax. This fly adapts to different casting styles such as roll casts or lifted/jerk-style casts.
