The Volkl Multi Trial Pro Pack contains four comfortable and very responsive multifilaments. Players looking to soften up their stiff racquet or hit a more powerful ball are encouraged to try these extremely well-built multis. Power Fiber II is Volkl's most renowned multi. It offers "best of class" feel and ball pocketing along with surprisingly good durability. V-Twist is comfortably crisp and has a slight texture for adding spin to your shots. This is a great option for the player who needs the comfort and power of a multi but wants to hit more effective topspin and slices. Rounding out the package are two sets of V-Feel, each with a different color. This extremely comfortable string benefits from a unique bonding process designed to offer longer tension maintenance. It has very controllable power for a multi.
