To split the thread Over complicated tenkara. In reflection I should have had a different title.
Like: Over Complicated Instruction or Over Complicated Documentation.
Regarding complexity in tenkara or just fishing.
I see a sort of a parallel with fishing and painting in its structure.
rod and line
Anyone can learn both disciplines. A beginner can even be very successful. It takes years to refine and a lifetime or more to learn.
As todoroki34 would say:
Painting is very simple in appearance but the inside is very complex
In both there are infinite approaches and an individual can choose the complexity they wish to draw into their approach.
