This is my favorite book about fly fishing. Art Scheck has a way of simplifying everything from knots to fly patterns.
Do we really need to know 1000 knots? After reading the book you walk away realizing the sport is almost always made overly complicated. Scheck gives you the knowledge you need to get on the water and catch fish without all of the marketing garbage magazines love to spout. Seriously, this book is void of all snobbery.
I went from buying everything to tying my own leaders and bimini tippets, and my fly box went from a mishmash of offerings to a selection of flies that make sense.
The book is outstanding, so pick it up.
