According to yonex: "The cushioned underside layer of the YONEX Super Cushion Grip reduces vibration, further enhancing the soft feel at impact provided by Shockless Grommets. Cushioning performance also helps protect the wrist, arm and elbow against shock-related injuries." I recently bought the RDS 001 MP and the cushion grip came on it, the demo had the same grip which i had been trying for about 2 weeks. My question is how well does this really work? If i replaced the grip would the feel of the racquet differ? As in vibrations and stuff? I like the feel of the grip but not as much as the Tecnifibre X-Tra.
