Here’s a brute fact: Accurate fly casting catches fish. Everywhere and of all kinds. The more accurately you place your fly, the more and larger fish you’re going to catch (over time, of course, and assuming other presentation factors are equal). Few, if any, of the expert anglers I know would quarrel with this concept.
But is it possible to cast too accurately? Is it possible that placing our fly too precisely can actually hamper our success? These are questions that, in my experience, rarely get asked or even considered.
