When the dry fly fishing is fast and I am catching many cutthroats in the mountain trout streams in the Rockies or brook trout in the Eastern mountain streams, my goal is to raise and hook many trout and then release them as quickly as I can so I do not stress them. My Pop Strike consists of setting the hook on the strike so I know I have fooled him, then two or three seconds later I release all of the tension on the fly line. This enables more than half of my trout to swim freely away.
