The Butterfly Fan Zhendong Super ALC is the second Butterfly blade that utilizes Super ALC plies, the newest advancement in Butterfly blade technology. These new plies offer a softer feel and more speed than the traditional ALC ply, increasing dwell time and power. As a result, players can generate a blistering combination of spin and speed. Players looking for a dynamic spin game should consider using Dignics 09C, the newest rubber in the Dignics line. With a tacky top sheet and a harder version of Butterfly Spring Sponge X, players can generate unbelievable spin with the new technology. Those interested in looping/countering topspin with sharp trajectories over the table have perfect options in either Tenergy 25 (slightly better for countering and smashing) or Tenergy 05 (slightly better for allround offensive play).
