Re: New Angling system....
I wouldn't call it a new system. They have been using this rigging for fishing egg patterns in Alaska for ten years or more. It can be affective and it does keep anglers from hooking fish deep and in the gills. The trade offs though are hooking fish outside of the mouth, possibly and eye as well as a few missed fish.
There is plenty of debate as to wether or not it is Koser with fly snobs, but until they prove to me that it is any more detremental to fish than standard rigs I will continue to use it on occassion.
