Absolutely one of the best articles I've ever read. Thanks for sharing.
My favorite water is a local spring creek, and I've devised a method of fishing nymphs and such by using a Parasol Emerger type fly as the indicator and dropping a bead-head nymph (usually a flashback Pheasant-tail) and then dropping a scud or smaller mayfly nymph, unweighted below the larger nymph. The fish don't seem to spook at the site of this type of indicator and often I catch fish feeding on the surface on the parasol fly.
Once again, thanks for the excellent article; it has given me some new ideas and strategies for fishing the PMD's on this spring creek that I haven't thought about previously.
"There will be days when the fishing is better than one's most optimistic forecast, others when it is far worse. Either is a gain over just staying home."
