The Crease Fly can, it has and it will catch most saltwater species that will eat a fly. It also will fish freshwater for Pike, Bass (large and smallmouth), and for Midnight Brown, leave the feathered flies at home. Neutrally buoyant on fast sinking lines; a popper/slider on top. It alone is gaining a reputation for West Coast stripers rivaling the Gurgler. This pattern has been discovered.
