I'm also a bit puzzled as to why anyone would want to spin in conditions like that. (I've just taken a look at the video for the first time.).
I've fished a lot on the Finn, a stunningly fine salmon river that forms the border between Counties Donegal (Southern Ireland) and Tyrone (Northern ireland) and which has accordingly been quite an interesting place to be over the past thirty years or so. The people who fish there are far from being tweedy aristocrats. They are, on the whole, very working class people indeed.
Very few of them, though, however rough their manners and speech might be, would spin over lovely fly water.
They fish the fly, not because it's posher, but because it's more satisfying.
