All Spin Wing Vanes are designed to be forgiving, give excellent bow and cable clearance, stabilize the arrow faster and improve accuracy. Their light weight produces more feet per second giving the arrow a flatter trajectory and retaining most of its kinetic energy. They have been shot at over 350 feet per second without adverse effects and can be used with recurve, compound bows and crossbows. Spin Wing Vanes have been used to take numerous medals and set many world records.
