But as much as I love trout, there are many reasons why fly anglers should branch out to other fish. I have to say that I get a little sad when I think of the many great species that get overlooked. And some of these fish will absolutely up your all-around game. If you want to be a better trout angler, chase carp. They're harder to fool. If you want to build some fish-fighting skills, try pulling on a shark with a fly rod. Trust me, that learning curve is a quick one. Even skills like learning how to work certain flies for trout get better when you work them on other species. For example, pike fishing can help you dial in on the streamer game, and figure out the strip-strike.
