Not forgotten Monk, just don't go to too many places where it is permitted. Rainbows tend to splash at flies too much.
I used to fish Loch Maree for the Sea Trout. It is uncanny how, when fishing in a bit of a wave, your fly can be skating on a crest, disappear into a trough and when the trough rises to form the next crest, there is just a dimple where your fly used to be, and the fly is two feet down, and the trout long since gone. I lost count of the times this happened to me.
I fish in Ireland for a week or so, most years, and it is still practised there, particularly in the "Duffers Fortnight"
