That's a pretty good video.
The only small quibble that I have with it was when he said "the longer the line, the harder the hook set will be." This is certainly true when fishing upstream or across, but he was fishing down stream when he said it. I find the a longer line down stream means you're less likely to pull the fly out of the fish's mouth on the hook set, making a but easier. (Of course it also means you have to pull the fish further upstream, giving it ore chance to get off.)
