New heptagonal shaped string developed for the higher-performance player. Allows a player to generate maximum power and greater ball bite for massive amounts of spin. Co-poly material is very responsive and provides lots of feedback. Excellent tension maintenance.
The sharpest string in the stable. An ace for every player for whom spin and control are vital. A "pain in the ass" for the stringers fingers - enjoy guys.
The newest, most interesting innovation of the last years! Minimum tension loss (no string moving). High durability and high dynamic. Excellent ball control.
