Several years ago I attended a Fly tying seminar put on by Dave Allbaugh, a guide and tyer from the central Pennsylvania area who teaches his clients how to fish using strictly soft hackled flies. His patterns looked so "buggy" and "fishy" that I wrote down the recipes for three or four and tied some later. His March Brown pattern proved to be an highly successful fish catcher, and I thought some of you might like to see it.
Hook: #14 nymph/wet fly (Daiichi 1710)
Thread: Uni-Thread 8/0, camel
Tail: Grouse tail barbs
Rib: Fine gold wire
Body: Twist dubbed hare's mask (a spun body would also work nicely)
Wing: Slips from mallard or grouse secondary, either folded or paired
Hackle: Grouse
