Dynamic Nymphing: Tactics, By George Daniel

In this book, Daniel shares details on tactics and methods learned from knowledgeable fly fishers across the United States, as well as from his competitors throughout many other nations, enhanced by own insights gained through experimentation and experience. Daniel gives a thorough explanation of the suspension system of drifting nymphs below a dry float or float, covering virtually every aspect: leaders, weighting, rigging, and how best to fish areas that are difficult or nearly impossible to approach any other way. He also provides comprehensive instructions on tight-line nymphing, a method of nymphing without indicators, from casting to maintaining line control from rod tip to nymph in various stream conditions, including glides, pockets, riffles and pools. To become a good nymph fisher, it is necessary to understand this aspect of the sport as well.

This book is a study of nymphing strategies: you won't digest the material in just one reading. It gives you thorough analysis of casting techniques, mending the line, and choosing the flies that can best produce for you if you fish them correctly, all presented in a technical manner. And finally, to paraphrase George Daniel, "This book is a melting pot of nymphing theories and tactics that will provide you with the tools to become a good nymph fisher."
If you are a serious student, the insights within these pages will help you catch more fish.
