Finn displays a hopper, a dry fly which floats on the surface, with an additional very small nymph, a wet fly that sinks below. "With this set-up, I get two chances. If the fish hits the nymph, the dry fly will drop under, and I set the hook. Or, the fish could just go straight to the dry fly.One time last week I caught a fish on both hooks with one cast!"
