Less is better
I usually only carry one box of assorted flies and then tippet, floatant and some hemostats. Other than that I like to take along a small, cheap backpack with a book to read along the stream, a thermos of tea and some cheese and fruit.
Now that I think about it, most of the room is taken up by non-fishing stuff! I like that.....
Many go fishing all of their lives without knowing that it is not fish they are after.
