The Catapult 10 V-Engine offers excellent power for a player's racquet. With a 102sq. inch headsize, a 67 RA stiffness and some useful swingweight (334 RDC), the Catapult 10 V-Engine puts a lot of stick behind the ball. Our TW playtesters found groundstrokes to launch off the stringbed of this racquet with excellent pace and spin. The response is both stable and comfortable with a somewhat dampened feel thanks to the Catapult grommet system. At net this racquet offers a nice combination of maneuverability and stability. There's ample pop for punching volleys deep and the dampened feel provides excellent comfort. Our testers found lots of pace and spin on serves with some noticeable hop on kickers. All in all a solid choice for the skilled player seeking some power and spin from his or her racquet. Best suited to 4.0+ level players.
