Need to make a lot of bridles exactly the same? This bridle board is a great jig for marking and cutting bridle lines. Easily made from materials you probably have laying around in your garage. http://kites.icelands.ca/misc/bridleboard.jpg
Stunt Kite Bridle info: This bridle will tilt the kite backwards in turns and has several advantages; it tracks better in sharp turns and gives a better start and faster flying and therefore more power. http://www.xs4all.nl/~pdj/bridle.htm
Dynamic Stunt Kite Bridle: The key feature of the dynamic bridle: depending on the pressure applied to one or both flying lines, the tow point automatically shifts up or down whilst still maintaining tension on all lines in the bridle. On an equivalent static bridle, one leg or more will go slack if the tow point moves from its “home” position. http://www.kfs.org/~abw/kite/boxbridle.html
