I have read many of the different fencing books on the market, and these two are the only that provide both logical structure and useful content. As one other reviewer has astutely pointed out, the authors have themselves produced many national champions, team champions, and olympic team members.
This book may be a bit pricey, but it is worth the money compared with the other books out there. The old saying holds true: "you get what you pay for."
As an epee fencer, I have to say that the section on epee is very well written. I have noticed that, in many fencing books, the author will only spend a page or two describing epee tactics/technique/theory. Usually, the theory consists of a few rambling paragraphs. Epee is given a much better treatment here. For one thing, the description of epee footwork put into words what I had trying to describe to begining epee fencers for years.
Good photographs too, especially the one of my friend Michael Feldschuh (with an astonished George Kolombotovich in the background) at the begining of the chapter on officiating. Also, the "models" demonstrating fencing actions do not look awkward (as those in other books often do).
In short, if you are a competitor, borrow it. If you want to become a coach, buy it and memorize it.
