Expert Review

This racquet sits in the oversize game improvement category and is designed around its primary performance strengths. The 115 in² head size boosts forgiveness and sweet spot size.

The 18x20 string pattern (open) influences spin access and launch angle. Performance-wise, it scores 100/100 for power, 60/100 for spin, and 20/100 for control, outlining its on-court behavior. Comfort levels are above average, supporting longer hitting sessions. It is best suited for beginner players.
