For the last few seasons this fly has taken the most fish of any pattern used. Normally fished 30cm under a big indicator fly like the Brown Wulff with a fluorocarbon dropper. This fly appears to imitate the sub surface mayfly nymph during its emerging phase and is as effective during a hatch as before. Fished best with a floating fly line. If fishing by itself try a very slow figure 8 retrieve, just keeping in contact with the fly.
