There are things in his book that are basic to say the least, but he does cover ground I've never read before.

The use of a spinning real (on a fly rod), the use of all Mono (no fly line) to name 2. When I first heard of them I rolled my eyes and figured I was in for a horrible read, but I was surprised to see he makes some excellent points. His writing style is a bit hard to take at times, but once I get past it I realized he has a lot of good information (often given again and again).

I think there are areas where most can skip. but when he describes drag, and how to minimize it or the benefits of an all mono rig I think it's worth the read.
