I've caught some smaller blackmouth and silvers with just a deep six (smaller size) and a long leader and a 4" coyote. I've also caught fish with a deep six out the back with a flasher and coho fly. They do have a lot of drag though and downriggers are preferable if you can put them on your boat. some days the deep six will out fish downriggers, but that is more the exception....probably means your gear is too deep.
