what is the best low end a kite can do on water

The higher the aspect the better and also the bigger the better. I would use anything at 16 and above. Fast turning is a must though thats where the higher aspect comes in. Lite wind kiting is more of a challenge then simply ripping at a nice cruising speed. A kite that is fast in the window but is a high aspect kite will shoot and pull in the window.
