I don’t really see the same considerations given to salmon flies as I have for trout.
Indeed. I wont name names as its their business (as in they make money from fishing) but I saw a catch report of several nice salmon caught in very very low water conditions. It was a remarkable achievement.
There was a photo of the fly, a size 16 barbed silver treble with a few whisps of hair tied to it.
The report said that the lucky angler had already lost two identical flies to lost salmon before his last "lucky fly" did the business.
My concern is that a salmons jaws are like crocodiles, they are capable of crushing, but they have little available muscle to open the mouth. If those lost fish had the treble stitching their mouths together with 2 or more points, those fish are probably now dead. They "may" have been able to crush down on the treble and bend it enough to dislodge it, but I doubt that would be possible if hooked near the front of the mouth.
I see a combination of barbs and three points, especially on a fine tippet for summer conditions, a big no-no.
