Following the enormous success of the Wing blades incorporating WSI technology in 2008, the range has been further extended to incorporate the a€˜Passiona€™ series. a€˜Passiona€™ is ... putting more energy into something than is required. That is just what the Joola technicians have done in producing the new range. The result is a series that creates total synergy between blade and player. Built using special CS (crystal-structure) carbon as a base, the blade has a totally new balance of spin and speed when combined with kiri and fineline veneers.
