Master angler and author Duane Redford delves into what the top 10% of anglers are seeing and doing differently from the fly fishing masses, and how they are consistently putting fish in the net in every situation. This work is a culmination of hundreds of hours on the river, observing and documenting insect, fish, and angler behaviors. It includes something for every level of angler from reading the obvious runs of the river to its subtle nuances; bug selection made simple, how to rig to attain a lively drift, recognizing and exploiting the X-Y-Z grids in a river run, tactics to get better now, and how to implement the Fly Fishers' Formula while you locate and effectively fish your "quarter mile" of river. This book is a comfortable read that takes you with the author as he describes the techniques and applications derived from statistical information and observation, for successful fly fishing on any river. 226 pages.
