I have just added a new addition to the River Fly Box: The GRHE nymph
Faced with a deep, fast run of water that just simply screams fish, this no-nonsense, tungsten-headed version of a Gold Ribbed Hare's Ear Nymph is my first choice.
It represents everything and nothing. It could pass as a cased caddis or a stone fly nymph. It may even suggest an olive nymph or even a shrimp. It matters not! What is important is that this fly will serve you well and persuade a take on even the quietest of days. This is an important fly for my early season trips when fish are hungry and there is plenty of water moving through the river. This is also a very useful nymph as a point fly on stillwaters.
