What’s the nymph really doing under there? How is it affected by the currents? And is the attached tippet dragging the fly unnaturally across, over, up or out of the natural, one-seam drift that our picky trout are waiting for? The challenge of nymphing is mercifully balanced by the frequency at which trout feed on these bottom dwelling food forms. So even if we get one in ten drifts just right, the rate at which we might fool fish makes this maddening quest for perfection more than worth it....
