Rickards.... My conclusion was the same. There really wasn't anything that earth shattering in there. Nothing really stuck, or stuck out. I might go peruse it again with preparation for lakes on my mind. He did convince me to pick up an intermediate line, which I'm anxious to use more and get more familiar with. He is very oriented towards biggest fish, oriented towards shallower water, very much prefers attractors and suggestive pattens to strict imitators..... And he really needs a better editor. That book could have been 1/2 as long. All fishing comes down the same thing: where are the various food items located, which food item are they choosing at this time, and then fly/presentation to match. He concentrations more on things he says are going to catch bigger fish. Personally I'd rather start out with a broader view, and would happily trade some numbers for some size. Love catching big fish--who doesn't--but I don't feel compelled to narrow the scope quite as much as he seems to. But to each their own. It's not going to hurt anyone to read his book, but it's not some sort of crucial work on the subject.
