We recommend the straps over plastic handles, the straps are very comfortable. These kites usually weight only a few ounces and can be flown indoors or in no wind. By simply walking in a backward and steady pace you can create an artificial wind. This is enough to fly these kites and perform tricks. We recommend any line length from 8 ft to 50 ft and 10-50 lb test.
Power is generated by flying inside of the wind window.
If you like speed and the raw power of kites, dual line parafoils are what you are looking for. On most dual line parafoils there is only a minimum wind required and the maximum wind the kite can handle is fairly high.
