Yonex-VCore Xi 98 Tennis Racquet-() Used by tour pros Juan Monaco and Bernard Tomic, the Yonex V-Core Xi 98 is made for players with plenty of power potential. The Integrated Power Weight System (IPS) places added weight at the 3 and 9 o`clock head positions to give the racquet face a greater moment of inertia, while high-density MicroCore material is placed near the 2 and 10 o`clock head positions to increase spin and stability...
