An older fly, Rainy’s Grand Hopper is one of our Top Hopper Patterns and has been a staple on U.S. West’s rivers for a long time, and it continues to deliver. The fly is not overly-dressy, but relies on the fundamentals of any good hopper pattern, and was one of the first to utilize foam. The Grand Hopper can also used as a mutant stonefly on the Yellowstone and South Fork of the Snake because it moves/chugs water.
