One of the best winter lure and fly for fresh and saltwater fishing. Winter fishing ether conventional or fly fishing, you want to use a slow sinking lure or fly. For lures one of the best is a Catch 2000 Jr. in black back, red and gold sides.. this lure fishes like a Cory, A Cory is good too. ,, let slow sinking an twitch slowly with pauses. Hang on the reds and trout will try to take your rod away when they hit it. This is winter fishing...slow retrieve also applies to freshwater.. With a fly rod use this fly, also a slow sinking and slow retrieve fly. The darker colors work best in winter over cast days.. and in darker water.
Good Luck!
