LEFTY KREH S SOLVING FLY-CASTING PROBLEMS contains detailed descriptions, instructional illustrations, and troubleshooting techniques that every fly fisher needs to know. Lefty offers unparalleled advice about how to cast in windy conditions, how to accurately change the direction of a cast, tame tailing loops, send flies deep, make casts to reach under low branches, and much more. Anyone who has ever missed a fish because of a casting problem (and who hasn t?) needs this book."
Step ! - do you fly fish (or have aspirations to fly fish)? If no, find another book. If yes, prepare to learn from a great instructor (in print).
Simple. Better Casting! Better Fishing!
Note added - I read the book, but I keep referring to it from time to time. So, I guess I really didn't finish it, since my fly casting is never finished.
