The original fly upon which the Sunray Shadow series of flies was based.   It is hard to find a fly with more solid credentials yet a reassuringly humble heritage and is one of the most classic of all British Salmon Flies.   Border Collie dogs were very popular amongst British farmers and local ghillies and their hair was perfect for this fly.   Simple and easy to tie yet exceptionally effective it became a standard pattern that has been used to great effect for generations.  It comes in many forms ranging from doubles or trebles to two inch aluminum tubes.  Fished square and fast or stripped back at pace it can provoke very aggressive reactions from otherwise ‘dormant fish.
