VCORE Xi 100 is a fantastic racquet for intermediate level players and also pro players, where it is the preferred racquet for Angelique Kerber. The Xi technology provides you with an extended sweetspot reaching towards the top of the frame. That technology is part of the reason the Yonex frames are unique as it is evident by the Isometric Square Head Shape that all VCORE racquets posses. Micro Core material is infused into certain points on the frame, which strengthen the upper part of the frame. This also creates extra weight in that part of the frame and helps make this a very stable racquet.
The upper sides of the frame have been enforced with X-Fullerene that improves the strength of VCORE Xi 100, which provides players with a stiff racquet able to produce plenty of power. This construction of the frame also helps reduce unwanted vibration and therefore creates a more arm friendly racquet. A better feel from the upper part of the stringbed also helps your game due to the unique structure of the frame.
The open string pattern on the VCORE Xi 100 provides lots of spin. The weight is only 11.1 ounces and combined with a 5 points head light balance point this allows the intermediate players to easily maneuver this racquet. All court players are going benefit from the capabilities of this frame. The swingweight of 305 also helps to make this a less demanding racquet while still being able to produce quite a bit of power.
