A mid-launch, low-spin profile with reinforced tip stability tightens dispersion while keeping feel lively. Ideal for players chasing speed and carry without ballooning, with weight options to fit aggressive or rhythmic tempos.

This shaft shows minimal signs of use. There may be slight, barely noticeable cosmetic imperfections like faint scratches or small marks, but the performance is not affected. The graphics remain fully visible and mostly untouched.
