Lovely location as always Mark. I am planning a trip up to Wales, hopefully this year, some waterfall photography is needed. As always great little chat, Personally I do go for the long exposure more often than not, however like you said a time and a place for it. I shoot long exposure and then get one with a faster shutter speed too. Because until I get home I never know what I will like, so cover all bases lol. As for right and wrong, its Photographys best feature and biggest mystery, When photography became a thing, everyone was saying sharp images are the right thing and then came along ICM lol, If there is another way of photographing something, someone will like it and someone will hate it.
