Here we have Leisenring’s take on the English classic Tups Indispensable. (Bonus points if you know the meaning of “Tups,” and its relevance to the pattern. Hint: it has to do with sheep mating. Really.) The original across-the-pond pattern was intended as an olive spinner imitation. But when I see this fly, I think Yellow Sallies, Suplhurs, and Light Cahills. Or we could just go with “Pale Wateries” and be done with it. Once again, best to leave it to the trout to decide what it is. Leisenring specified a heavy wire hook to help sink the fly: “I have no use for a weighted nymph because they do not swim naturally.” (Take that, future Euro-nymphers!) The Tup’s Nymph was another high confidence pattern for Big Jim, as evidenced by this statement: “This is the best all-around nymph I have found.” Try it on point on your three-fly team, or as the top dropper on your nymph rig.
