This shaft is very easy to handle, and while it feels solid, it swings exceptionally well! The Pro White 1K series utilizes the "white-based" characteristic of high tip stiffness to stabilize head behavior, achieving directional stability and a low-spin, powerful trajectory with "impact that hits the sweet spot." The butt section features 1K cross, which is flexible and effectively reinforces the shaft, allowing for a deep lag at the transition and a stress-free swing through impact. The grip is an Iomic Sticky JUMBO, which is recommended for those with large hands or those who tend to hook the ball!
