◆ Released as a 10th-anniversary model ★ This is a shaft from the WACCINE Compo series. ★ Shaft stiffness → The shaft has one virus-themed mark on the logo side, so the flex is (R). ◆ Since the shaft flex is (R), it flexes quite a bit when you swing, but perhaps because there isn't much (bending or twisting), it feels like it firmly follows through your swing, providing excellent responsiveness. It's a shaft you can swing aggressively, making it fun. (This is my personal impression.) Also, I think [women with above-average power can also enjoy it, so please consider it]. ★ Used with Qi10 and Qi35 drivers. ★ Shaft weight (including grip and sleeve) → 100g ★ Length → Approximately 1118 mm (44.01 inches) from grip end to sleeve tip ★ Condition - Shaft → No noticeable scratches. Grip → No wear or pressure marks.
