The introduction of the Idea a12 Hybrid coincides with the launch of the high-performance ProForce VTS hybrid shaft from UST Mamiya. * Spring-like effect across the face produces a hotter face and increased ball speed. * Tour-proven design and shaping with the addition of Velocity Slot Technology for increased forgiveness and distance. * The hotter face combined with higher launch produces increased distance and reduced spin. * This shaft has quickly become a favorite used by Tour pros and perfectly complements the a12 clubhead to deliver exceptional performance and playability.
