California fly fishing legend Ralph Cutter shot some video of trout repeatedly eating a Golden Stone nymph, while his wife (the angler) reported only saw the leader twitch once.
From the YouTube entry:
Golden trout eating nymphs every drift, but the (very experienced) fly fisher never feels a tug and only once sees the leader twitch. Split shot is painted orange for visibility (trout don’t care) and nymph is treated with desiccant to make it shiny.
This, I believe, offers absolute proof of what I’ve always said: Nymphing is a tawdry technique practiced by degenerates, Satanists and PBR drinkers. “How is it proof” you ask?
It just is.
