This is a shaft with a sleeve for a driver pin. It's a 60S. It has a flex feel throughout the entire length. It pursues the comfort of the overall flex. The appeal of "Zaffiro2" is that it can generate maximum flex with minimal power. You can leave the flex behavior to the shaft and concentrate on plane control from the backswing to the follow-through. Furthermore, the stability produced by the low torque improves operability. There are no blind spots in the whip that can be controlled freely. "Zaffiro2" reflects a brilliant trajectory in the eyes of technical swingers who emphasize control.
