How your fly is presented to the fish is critical. In fact, it's more
important than the exact pattern that you choose. The fly has to swing in
the current at the right speed and depth in order to trigger a fish into
striking. You know, it's all too easy to get hung up on fly patterns and
your casting when you're fishing salmon or steelhead. Those are fun things.
But it's far more important to worry about your fly swing speed and the
depth at which your fly is swinging. The fly has to be off the bottom but
fairly close to the bottom, and it has to be swinging at a kind of slow
walk kind of swing, so pay attention to those things when you're fishing
for salmon and steelhead.
