Its greatest feature is the fusion of VTC technology and a double-kick design. By intentionally reducing the bending rigidity in the grip and tip sections, the shaft progressively accelerates from the top of the backswing through the downswing and into impact.\u003c\/p\u003e\u003cp\u003eThe common perception of a soft shaft being unreliable in feel or lacking power at impact is resolved by VTC technology. It optimally controls shaft torsion, transmitting the snap-back energy to the ball without waste.\u003c\/p\u003e\u003cp\u003eThis allows even golfers who lack confidence in their swing speed to clearly feel the shaft flex, naturally improving both head speed and initial ball velocity. It facilitates better timing, achieving a stable trajectory and greater carry.\u003c\/p\u003e\u003cp\u003eIt caters to a wide range of golfers, from beginners and average players to advanced and intermediate players seeking to increase their distance.
