"If he's right, then how do we make a cast, land the fly line on smooth water and not spook fish?"



My response would be that when the fly line lands on water directly over fish, those fish will be spooked. If you know where the fish you are trying to get your fly to are, you would need to use a longer leader and tippet combination so that your fly line lands further away from the fish you are trying to catch and your leader/tippet lands softly on the water.

Just my thoughts and opinion only.....
