Met him today at our TU meeting and he was certainly one of the most approachable people I have met in FFing.
that said, I haven't finished the book, but after seeing his presentation and comparing it to my interpretation from the book I was glad to see that the book was pretty much straight forward about the techniques...or at least the ones I have read about so far.
It is interesting to note how little of a hesitation will trigger George to set. its very little, and depending on the situation the slightest hesitation in the line signals the set.
he stressed good positioning on the stream and really making sure the nymphs are getting into the "right" current and at the "right" level of the water column.
he also went over when long distance casts are appropriate and I was surprise to see the conditions in which he was executing this tactic.
all in all, this style of fishing appears to be very systematic and surgical. you can easily see that it has been developed from a competitive origin.
my 2cents:
when you hear about this technique you may be tempted to believe that it is revolutionary, or that it is necessary to learn or any of the other crazy thoughts that run through our minds when we see a "new" product or fly or tactic. Rest assured that this is not a "game changer," Fly fishing....fishing period, will always be about what you make it.
a friend of mine once said that "all fishermen evolve, some further than others..." he went on to say that most fishermen start out wanting only to catch a fish (just a singular fish!), then they want to catch more fish, then bigger fish, then they want to catch the MOST fish, then the BIGGEST fish and finally, some people, after they have "done it all" they want to teach others and see the joy on someone else's face when they catch A fish. "And now you know...the rest of the story"-P.H.
