36" Lake Nymphing leaders:are built using additional thread at the butt section as well as the length of leader. We all know that lake fishing can bring that fish of a life-time and we want the leader to withstand any such strike. These leaders sink fast. In all of our testing, the 36" treated nymph leader had a better sink rate than any of our sinking fly lines. This allows the fly/tippet/leader to sink without creating a belly in the fly-line. These Lake Leaders have been receiving great reviews from our current customers. Typically, lake fishing require longer tippets because the fish have more time to check out your set-up. 5-6 feet is more than enough.
