This is my take on it. I personally find no enjoyment in videos that focus entirely on yoyoing. It may sound silly, but I enjoy the scenery almost as much as the yoyoing sometimes, and that is key to it. I want a bit of a story or something to mix it up.
Aaron Davis has a wonderful Basement Sessions series on his YouTube. Scenery is bland (it is a basement after all), but the video features multiple people with different styles with typically both kendamas and yoyos.
