I've always used spinners and spoons so I don't know about what fly to use but as for the area I always fish Whidbey island. Look for a cobble stone beach, with minimal current and if you can find salmon smolt or other small fish in schools then your chances for success are greately improved. Last year salt water cutt throat was closed, i don't know whats going on for the year ahead but watch the regs closly because it can change at any moment.
