Does the idea of using a Mop Fly offend you? Well, then perhaps you can get behind the way that Tim Flagler of Tightline Productions uses that mop material to create a cool-looking dry fly. Tim’s Mop Hopper (how could he resist calling it the Mopper?)
GFA stands for “General Foam Attractor”. The GFA Hopper pattern was created by Walter Wiese out of Parks Fly Shop in Gardiner, Montana. This pattern is easy to tie and looks and fishes well in all colours.
