Not me, no tree climbing for no $20 fly, no way.
If I bought one of those it would be like some other super fancy flies and some simply elegant flies that I've acquired over the years as examples of what can be done and used only as pattern stock/inspiration at my table or occasionally show to the trout fishers at the park. I wouldn't plan on casting it more than a time or two. .
I have an appreciation for beautifully tied flies, but only in their ability to catch fish.
