If you’re on to a killer pattern, why change it out? If you require less weight or more weight, then the Dore’s Depth Control series is a pattern that you must have in your fly box. Based on the ubiquitous Pheasant Tail Nymph, the Dore’s Depth Control is a size 14 nymph you can fish in any river, lake or stream in NZ. Switch the about as the depth, flow and fish dictate, and watch your catch rate climb.
