{"product_id":"nymph-head-heavy-metal-wd-40-fly","title":"Nymph-Head Heavy Metal WD-40 Fly","description":"\u003cp\u003eThe Nymph-Head Heavy Metal WD-40 Fly updates a classic tailwater pattern with a tungsten bead to help you reach fish in deep currents. This fly specifically imitates small mayfly emergers and midge pupae that trout eat constantly throughout the year. It is a must-have for your fly box when targeting selective trout in technical fisheries where depth control is vital.\u003c\/p\u003e\u003ch3\u003eWhat It Imitates\u003c\/h3\u003e\u003cp\u003eThis pattern mimics Blue-Winged Olive emergers and midge nymphs as they struggle to reach the surface. The slim profile and mallard flank wing case look exactly like the natural insects found in many rivers during a hatch. It captures the look of a vulnerable bug that trout cannot resist.\u003c\/p\u003e\u003ch3\u003eHow To Use It\u003c\/h3\u003e\u003cp\u003eFish this fly deep using a tight-line nymphing rig or suspend it under a strike indicator to drift near the riverbed. It serves perfectly as a heavy point fly to drag lighter nymphs down or as a dropper in a multi-fly setup. Use it to probe deep pools and pocket water where trout hold during the middle of the day.\u003c\/p\u003e\u003ch3\u003eWhen To Use It\u003c\/h3\u003e\u003cp\u003eThis fly shines during cloudy days when Blue-Winged Olives are hatching or anytime midges are active. It is an excellent choice for winter fishing or low-water conditions when fish demand smaller presentations. The weight allows it to work well in faster currents where unweighted flies would wash away.\u003c\/p\u003e\u003ch3\u003eWhy We Like It\u003c\/h3\u003e\u003cp\u003eThe addition of the Nymph-Head tungsten bead gives this famous pattern the ability to sink rapidly without adding split shot to your leader. We like how the durable coating on the bead matches the body color for a seamless look. It offers a precise presentation that gets to the feeding zone faster than traditional versions.\u003c\/p\u003e\u003ch3\u003eComparisons\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eNymph-Head Heavy Metal WD-40 Fly vs Zebra Midge:\u003c\/strong\u003e The Zebra Midge is a simple thread body midge larva imitation with wire ribbing and a bead. The WD-40 adds a tail and a prominent wing case to imitate an emerging insect rather than just a larva. Choose the WD-40 when fish are keying in on emerging midges or BWOs rather than the bottom-dwelling larvae represented by the Zebra Midge.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eNymph-Head Heavy Metal WD-40 Fly vs Rim's RS2:\u003c\/strong\u003e The RS2 is a lightweight emerger pattern often tied with a foam or CDC wing to float in the surface film. The Heavy Metal WD-40 uses a tungsten bead to sink quickly and target fish feeding deep in the water column. Select the Heavy Metal WD-40 for tight-line nymphing or fishing deep runs where the RS2 would not sink fast enough.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eNymph-Head Heavy Metal WD-40 Fly vs Bead Head Pheasant Tail:\u003c\/strong\u003e The Pheasant Tail is a generic mayfly nymph with a natural quill body and legs that creates a buggy silhouette. The WD-40 features a slim thread body and lacks legs to mimic the sleek profile of midges and small Baetis emergers. If you need a smaller and more streamlined profile for selective fish in clear water, the WD-40 is the superior choice.\u003c\/p\u003e","brand":"Nymph-Head","offers":[{"title":"Black \/ 18","offer_id":48477990945001,"sku":"SKU-HM-WD-BL-18","price":2.49,"currency_code":"USD","in_stock":false},{"title":"Black \/ 20","offer_id":48477990977769,"sku":"SKU-HM-WD-BL-20","price":2.49,"currency_code":"USD","in_stock":false},{"title":"Brown \/ 18","offer_id":48477991010537,"sku":"SKU-HM-WD-BR-18","price":2.49,"currency_code":"USD","in_stock":false},{"title":"Brown \/ 20","offer_id":48477991043305,"sku":"SKU-HM-WD-BR-20","price":2.49,"currency_code":"USD","in_stock":false},{"title":"Grey \/ 18","offer_id":48477991076073,"sku":"SKU-HM-WD-GY-18","price":2.49,"currency_code":"USD","in_stock":false},{"title":"Grey \/ 20","offer_id":48477991108841,"sku":"SKU-HM-WD-GY-20","price":2.49,"currency_code":"USD","in_stock":false},{"title":"Olive \/ 18","offer_id":48477991141609,"sku":"SKU-HM-WD-LV-18","price":2.49,"currency_code":"USD","in_stock":false},{"title":"Olive \/ 20","offer_id":48477991174377,"sku":"SKU-HM-WD-LV-20","price":2.49,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0749\/1846\/1673\/files\/nymph-head-flies-nymph-head-heavy-metal-wd-40-fly-1199952145.jpg?v=1761646090","url":"https:\/\/www.tridentflyfishing.com\/products\/nymph-head-heavy-metal-wd-40-fly","provider":"Trident Fly Fishing","version":"1.0","type":"link"}
