Re: soft hackles for brook trout? (not on swing)
Soft hackles can be fished upstream, across, downstream, all of these in combination (as described by Dave Whitlock in a wet fly article in Fly Fisherman magazine last year) and even as a dry or "barely wet" fly. They are a blast to fish and will work well on brookies.
For more information on soft hackles, I recommend the book by Allen McGee, "Tying and Fishing Soft-Hackled Nymphs" and also Davy Wotton's DVD "Wet Fly Ways. "
btw, that is a great looking fly, noreaster. What are the tag and main body materials? What hook sizes do you prefer?
