I most always have a few tied both wet and dry in my boxes. Like it mentioned in the article it does match nicely the Leukon hatch on a summer/autumn eve. I had one on one eve when the white millers were coming off and as it was too dark to really see, didn't know what hit my fly and took me into the backing. I had caught a couple 14 inch or so trout so assumed it was their big daddy! Turns out it was a huge Pike Minnow in that 5 lb range. What a strike and fight!
