"If fishing is like religion, then fly fishing is high church" Tom Brokaw
Sometimes the simplest things work the best. Back in the early 1970's a writer by the name of S.R. Slaymaker (he wrote for the hook and bullet press about fly fishing) wrote about a simple generic nymph that was breathtakingly simple to tie and a virtual trout magnet when fished right. The fly had no name and still doesn't as far as I know although it looks like one of Sawyers nymphs. Slaymaker used mink for the body. I once had some raw mink but it's long gone so I use Australian possum or hair mask.
Hook - Nymph or standard dry fly hook sizes 12-14
Weight - your choice wrapped around the hook shank (resist the temptation to stick a bead on it. This is fly tying, not lure making)
Tail - A few partridge fibers or a tuft of fur
Rib - ultra fine copper wire
Body - Australian possum or hare's mask dubbed loosely and then secured down with wire. Use that little carding tool that we all have but never use to pick out the dubbing.
Above is my life time supply of Australian possum dyed olive or yellow. It has that kinky texture that works great underwater. I would guess that good old American possum would work just as well. Over the years I've taken to touching up the color to suit my taste (actually the trouts taste) with Sharpies. I've tied up some nymphs with yellow fur and then hit them with a black Sharpie. Just enough yellow shows through for a nice effect.
The Swift - The stretch from the Gauge through Cady Lane has been fishing well. At 50 cfs and little snow it's been rather pleasant. The best time of the day is between 10 am and 2pm especially when the air temperatures push past 40 degrees. A drab Partridge and Olive SH ruled the day on Friday laying to rest the belief that only bright colors work in the Winter.
