After reading the question on here regarding dropper knots and spying the above book on my bookshelf today I thought a mention on here was in order..

The Author is Roger Fogg and I consider the book is not that well known it is a bit of a bible on wet fly fishing with spiders or soft hackles. Its Chapters cover history and modern day techniques , tackle and fly tying. It is a book that is found on the shelves of anglers who take their North country spider fishing seriously . If you can source one in the USA its one that is in my opinion worth buying.
