The Yonex E-Zone Xi Rally offers an ease of swing with a comfortable response. The new Xi expands the sweetspot for better consistency, reduced vibration and enhanced power. From the baseline, our team found themselves hitting deep, penetrating shots without much effort. Thanks to the open 16 x 19 string pattern, slice and topspin shots had plenty of bite. The Quad Power System combined with the Isometric head design provided a very stable frame for a solid feel. On serve, our TW playtesters took note of how easy it was to swing; generating plenty of both spin and power. This racquet is great in stock form but lends itself easily to customization and addition of weight. We highly recommend players from the 3.5+ level to take this one out for a demo.
