Query: Much better with holes

While Drew Heywood is an excellent author - this book will not be one to wind up in his Hall of Fame. This book was chock full of inaccurate statements, misleading comments, and poorly thought out statements. Using this to study from, or even using it as a reference would be a mistake. I found it very tough to read, and most of the time found it downright frustrating. I would, however, recommend it for target practice. The book becomes much more valuable (not to mention, lighter) after substantial portions of it are removed with a large calibre hand gun. Surprisingly, the readability doesn't suffer in the least. Seriously though, this book is terrible and the back of a cereal box would make a better study guide.
