Don't underestimate the maneuverability of a single line kite. The fighter type designs can be flown just about any direction you desire. It just takes skill and practice. Try a "Hata" from the "Into The Wind link I posted. It will fly in up to 40 mph winds and can be flown very aggressively with a single string and no tail. Put a tail on it and it becomes a docile children's kite.
