Volkl V-Star is one of the most comfortable co-polys available. This string is a great option for the player who wants the spin and durability benefits of a poly-based string but not the high stiffness and off-center shock for which the breed is known. V-Star also has above average power for a control string. All in all this is a great option for the player transitioning into a poly-based monofilament. It's also ideal for all those poly veterans who want to give their tendons a very smooth ride
