Good point. I'm convinced some larger trout get to the point where the sound/light/reflection disturbance of a small object hitting the water gets interpreted more as a dinner bell than an intruder alarm.
I've started using an AirFlo poly leader for dries as well, and so far, I'm pleased. Not as smooth casting as a furled, not as graceful of a lay-down, but once its on the water it floats higher for easier mending, has a nicer lift-off, and almost no spray.
