I almost never write about the art of fly casting as there are many who do it better than I and can draw or photograph so very proper the positions, angles and so forth used in the art of fly casting.

However I will say that a technical perfect fly caster isn't always the best fly angler. Fly fishing is a blend of fly casting, knowledge of insects that the trout feed on, knowledge of the trout and understanding of the water types the trout are found in. That is coupled with knowledge of the fly patterns used to deceive the trout on the waters we fish. [The same things applies to warm water and salt water fly anglers]
