The Yonex RQS 11 has a lot to offer in terms of maneuverability and comfort. The light feel of the RQS 11 allows for good control and manageable power. The signature Yonex flex is noticed throughout the whole racquet and provides a fluid response. Accurate shots are a certainty with this racquet as its stringbed controls the pop but still leaves room for plenty of spin. The Yonex RQS 11 is ideal for 4.0 level players looking for fluid mobility and control. This is the racquet of choice for Martina Hingis. Specifications: Head Size: 100 sq. in. / 645 sq. cm.
