VCORE Xi 98 is a terrific racquet for players at the 4.0 NTRP level and all the way up to pro players. This is the racquet used by Juan Monaco and Bernard Tomic. The Xi technology ensures you get a large sweetspot that is extended towards the top of the frame. This is what makes the Yonex frames unique as it is easily noticed by the Isometric Square Head Shape. Micro Core material is added to certain points on the frame as well to strengthen the upper section. This also adds weight and therefore stability to this part of the racquet.
X-Fullerene has been implemented in the upper sides of the frames to improve the strength and gives you a remarkable stiffness, which is responsible for more powerful shots. This frame construction helps reduce much of the unwanted vibration and therefore creates an overall arm friendly racquet and a better feel on shots that touches the stringbed in the upper part of the frame.
With an open string pattern the VCORE Xi 98 provides plenty of spin. The reasonable weight of 11.4 ounces combined with a 6 points head light balance point aids to the phenomenal maneuverability of this racquet. Baseline players and aggressive net players alike can benefit from the capabilities of this frame. The swingweight of 311 makes this a less demanding racquet that players on the ATP tour normally prefer, which can be attributed to the excellent technologies developed by Yonex.
