The Yonex PERCEPT 100 Tennis Racquet takes up the mantle of the VCORE PRO 100. At 10.6 ounces unstrung, the PERCEPT 100 is the easiest model in the line to play. The racquet uses the FLEXCON System; a tapered and elongated box-frame design for greater precision. Yonex' Flex Force graphite means the racquet can flex, but it snaps back quickly for greater spin and ball acceleration. Vibration Dampening Mesh is NOT in the PERCEPT models. Instead, Yonex added a transparent film between the graphite to enhance flexibility called the SERVO FILTER. The new technology reduces unwanted vibration by 13%. While FLEXCON and SERVO FILTER create a more flexible shaft, Yonex increased the amount of graphite in the racquet face for a 3% increase in stability at impact. Think comfortable flex in the shaft but with a firmer and more powerful racquet head. The PERCEPT 100 offers more power than the 97 models thanks to the larger head and thicker cross-section. However, the elongated shaft design and constant beam deliver control characteristics as well. Features: -New Elongated shaft design puts the focus on control and precision -SERVO FILTER filters unwanted vibrations but allows for improved feel as well -100 square inch head for added forgiveness -Isometric head shape creates a larger sweet spot
