I mostly fish for brown trout in Scottish lochs. I also occasionally fish for salmon and although I don't consider myself a salmon angler, and know nothing about it, I'm lucky enough to fish on Lewis and so I catch what many might consider a lot of salmon for the few days per year that I devote to it.
However, I have access to a little spate river in the Hebrides which, I'm told, gets a good run of sea trout and this year I might put my mind to catching a few, or at least trying to. I've had a previous bad experience of sea trout fishing in the Hebrides on a loch with a friend who took 22 fish for the day to about 5lb and I had, well, one about 6 inches long. :-)
I have the Hugh Falkus book, a limited intellect, and a few sea trout flies on order including some of the medicine/sunk lure/floating lure/secret weapon type that i consider to be "big" in keeping with the recommendations in the book. In a break with tradition I don't wish to use a net or a handgrenade.
So, is the info in the Falkus book still considered worthwhile? Is it worth fishing the flies he suggests in a small spate river in the Hebrides? Will fish actually move on such a small river even in low water? Is it actually necessary to fish at night? Any other hints and tips? (Can you tell that I know nothing at all about this?)
For reference here are some photos of the river, in fairly low water, just to give an idea:
