20 Incher

The 20 Incher is a highly effective nymph pattern designed to imitate large stonefly nymphs and other sizeable aquatic insects. This robust fly is known for its ability to attract big trout, especially in fast-moving waters where larger nymphs are a primary food source. The 20 Incher features a realistic segmented body, typically made with peacock herl and chenille, combined with rubber legs for added lifelike movement. Its dark, earthy tones help it blend seamlessly with the natural environment, making it an irresistible target for hungry fish.

Crafted to withstand tough conditions and aggressive strikes, the 20 Incher is tied on sturdy hooks that ensure durability and reliability. Its size and profile make it particularly effective in rivers and streams where stonefly nymphs are prevalent. The weighted body ensures that it sinks quickly to the bottom, where it can be most effective in mimicking the natural behavior of stonefly nymphs clinging to rocks and debris.

To use the 20 Incher effectively, fish it as a nymph. Cast it upstream and allow it to drift naturally with the current, ensuring it bounces along the riverbed. Using a strike indicator can help detect subtle bites. The 20 Incher is especially productive when used in tandem with a smaller dropper fly, creating a multi-fly rig that increases the chances of a strike. This pattern is most effective during the spring and early summer when stonefly hatches are at their peak, but it can be used year-round to target big, wary trout in various water conditions. Whether you are fishing in fast-moving streams or deeper pools, the 20 Incher is a must-have fly for any serious angler looking to land trophy-sized fish.
