Wotton has two great videos there, Wet Fly Ways and Midge Magic Fishing. Both are absolutely outstanding, and I learned a ton. He covers all the topics: rig, flies and techniques. Basically, it feels like you’re taking a private clinic with him on the river, as he shows what he does to catch many large fish.
Fly fishing is truly amazing. It offers a life-long ability to learn, expand your skill set and up your game.
