Rich,

You asked, "How well do they fish?"

In the write-up,
"So well in fact that I used a Green Drake dun, tyed in this style, to catch a 20 plus inch brown at the recent Roscoe Fish-In. I saw the trout rise to a natural and on the next cast put the fly over the fish. After what seemed like 10 minutes I released him. A big question about this fly is its durability. I did not have a chance to examine the fly after I released the trout because I cut the fly off at the tippet. It might be a 'one and done' style."

That is about all I can say until further use. I'm hoping others will try to tie and use flies of this style and report their experiences.
