I agree that trout taste lousy, but brookies aren't a trout. It's a char, or in the salmon family if you will.
Not sure i'd call them stupid either. Catching a big trout from a tailwater on a fly is not easy. Even harder to land with a small tippet. They'll dive under rocks everytime.
All these trout were caught from a short driving distance from where I live. Not what i'd call small, and not easy on light fly rod gear.
