This racquet sits in the power category and is designed around its primary performance strengths. The 100 in² head size boosts forgiveness and sweet spot size. A stiffness rating of 69 RA results in a firmer, more responsive feel at impact. With an unstrung weight of 300 g, the frame adds stability through mass. The 16x18 string pattern (open) influences spin access and launch angle. Performance-wise, it scores 100/100 for power, 80/100 for spin, and 40/100 for control, outlining its on-court behavior. Comfort levels are above average, supporting longer hitting sessions. Its characteristics suggest a higher potential for arm fatigue if paired with stiff strings. It is best suited for intermediate players.
Player discussions often describe the Yonex Ezone line as a 'power-with-control' frame: lively and forgiving with a modern sweet spot. Comfort feedback is mixed—many find it playable and comfortable, while some report arm/wrist/shoulder irritation, often tied to how firm the overall setup feels. Overall sentiment: great all-around performance, but comfort can vary by player and configuration.
