Butterfly Fan Zhendong ALC and Innerforce ZLC both suit advanced offensive players but emphasize different qualities. Fan Zhendong delivers crisp, direct performance through proven Viscaria-class ALC construction, with outstanding dwell for heavy topspin. Its thicker handle benefits larger-handed players, and it pairs seamlessly with diverse rubber types from Chinese tacky to European high-tension sheets.

Innerforce ZLC is distinguished by its inner ZLC construction, which preserves the woody feel rare in carbon blades while maintaining excellent balance of speed, spin, and control. Works across all ranges from short-game touch to mid-distance looping with a large sweet spot and low vibration. Both are premium options; however, Innerforce ZLC is discontinued with elevated resale prices, while Fan Zhendong remains current and offers established durability.
