The Green Copper John Nymph Barbless combines a dense copper-wire abdomen with a green finish and a recognisable nymph profile. It sinks quickly and can suggest caddis larvae, olive nymphs or other compact aquatic food while retaining an attractor element.
Use it in deeper runs, pocket water or beneath an indicator. Keep the drift natural and use its weight to support a lighter dropper where appropriate. Its profile and movement make it a strong choice for turning a quiet drift into a take.
