An excellent post ! And it should provoke further disscussion about nymph fishing, and further thought.
Tom Rosenbauer wrote an Orvis introductory to fly fishing book that hinted at just such a concept; again, most attention is given to currents when dry fly fishing, but not necessarily to sub-surface nymphing.
I find most of my nymphing is done with a 'tight line'and 'high sticking' (Leisering). Though I have used indicators, I find that I have had more success without them.
On the surface, these current variations are most evident and called "eddys", is there a name for sub-surface current variations ?
