Crunchers are a fantastic way to naturally fish for fish. Great fished as a team of 2, 3 or 4 with a slow retrieve staying in touch. Or on a washing line method. Best fished on a floating line.
For example a 3 fly set up you may fish with a leader set up such as 7 foot to first fly, 4 foot to 2nd and 4foot to point fly. Stay in touch with figure of eight retrieve and odd jerk. And just wait for the fantastic take!
