The new olive nymph called Tactical BQ4 Devil BL Nymph is our olive fly from our series of Devil Nymphs. It is a great all around nymph and should be in everybody fly box. The fly works great for trout and grayling and catch constantly from the first part of the season till late in Autumn . Can be set on a dropper or as a pointer fly in the same time. We have friends who use this fly in a team, smaller on a dropper and a heavier one on tip of the line
