I had never thought of kite tails as detrimental to the kite, but I now I can see your point, Jim. When I saw the kongzhus with their trailing wind socks it looked like just poi swinging. And I guess something similar happens to the top. Still, it is fun to do.
Perhaps, instead of the ribbon, a shorter string attached to the upper tip would allow new moves while keeping the "top" feel. I think much more experimentation is required.
