Euro nymphing is an elegant, tight line solution. But don’t limit yourself. Why not use the tight line tools (leaders and tactics) for more than just euro nymphing?
Use it for fishing a tight-line style of indicators. Use it for dry dropper or even straight dries. And use it for streamers, both big and small.
Refining these tactics is the natural progression of anglers who fish hard, are thoughtful about the tactics and don’t like limitations. I know many good fly fishers who have all come out the other side with the same set of tools. Because fishing a contact system like the Mono Rig eventually teaches you all that is possible . . .
