I must admit I was somewhat overwhelmed to see everyone maligning (no pun intended) the Sockeye.
The biggest trouble with fly-fishing for the Sockeye is that they do not readily come to the fly.
Unlike Steelhead and other salmon; the Red (Sockeye) just do not come to the fly.
Perseverance and patience is the key to game.
It is like fishing a traditional dry for Steelhead verses a skated fly.
One is going to be hard and the other is going to be very difficult.
But that is another thread.
