Yonex EZONE 98 racquet swings easy for a player's racquet, and it has an outstanding combination of spin and precision. This model comes with an updated Isometric head shape. Yonex has also retooled the grommet system with its Micro Offset Layout technology, which enables the strings to soak up greater vibration at impact. It also include the use of a hyper modulus graphite (Hyper-MG) in the upper hoop. The upshot, according to Yonex, is less frame bending at impact, resulting in greater energy transfer to the ball. As a result, this racquet feels a tad firmer but it is also more powerful than its predecessor.
