I was fishing for silvers in Kodiak last fall. Mostly I used flies I made. In a FF shop (near the Russian River, the shop has moved from Kodiak City to this place) I bought some flies. The hook was "attached to the fly" with a 40lbs (or so) line (sorry, can explain better). So, the fly-hook was flexible. I had some good fishing with these kind of flies. For trying, I bought ESL and other flies, all with this 'system'.
I guess, many of you know these flies and the name of this type of flies.
If one of you could send me a picture and/or the name of it, I would be happy. I am writing my kodiakblog and like to note this.
Sorry, the blog is written in german.
