I love emerging mayfly patterns. I'd argue that they're the most important mayfly imitations to have in the box- picky fish often prefer them over dun patterns, and in blizzard type hatches they often attract more attention than adult or dun patterns. And, I hate tying parachutes for some reason...
A favorite saltwater fly of mine. Designed to be essentially foul free, mostly bulletproof and loaded with lightweight, swimmy materials. Incorporating a tungsten bead for the action it provides, not so much the depth advantage although it will get deep if you allow it. I tend to strip too fast...
