Gold Bead Prince Nymph
Another classic that should not be missing in your fly box. Gold Bead Prince nymph. It does fine in Dutch waters for the roach and perch. But on the streams this is one of the classic patterns to use. And it has brought so many fish to the net and it will always do. But please try it at the trout-ponds as well. It can cause surprises when everyone is fishing blobs, boobies and sinking lines.
