Nice video - thanks for sharing!!! The first video was made in Germany and we do have some really nice places for Zander. One of them is the Edertalsperre, a dammed lake in Hessen, where they catch every year a good number of that fish. But Usually they are staying deep in the water so that it is not so easy to reach them with a fly.
I never caught one, but after that video I start to think on that challenge
