Note: for made the Kaufmann Stone I prefer use a “coipo” dubbing, the coipo is a patagonian otter. It has a spectacular fur with guard hairs that allow amazing effects in large nymphs. Dyed or natural to contrast guard hairs and coat achieves a great look.
Black, browns and grays are the best colors.

This fly created by Randall Kaufmann is for me one of the best examples of balance between realism and impressionism in a copycat fly, no element in its design removes feeling of life and texture and provide a very good aspect of realism.
Since its appearance was the archetype imitator stone fly nymph and in my case in particular made a great impression and represent a great influence on the concept of what should be a fly for fishing.
There are variants of this fly with metal beads heads and rubber legs that seek to contribute even more effectively to fly one of the best ever designed.
Patagonian environments in the most effective colors are black, dark brown, gray and hares ear.
