Revolution is a hexagonally shaped co-polyester string from Solinco, a company that specializes in the production of firm polys for advanced players. For our team, this shaped co-poly had the phenomenal blend of spin and control that we found with Solinco Tour Bite, a favorite at the collegiate level. What separated Revolution from Tour Bite was the feel. Despite earning a fairly high stiffness score in our string lab, Revolution managed to play with a surprisingly low level of vibration and off-center shock. However, the most salient feature of this six-sided spin monster was the confidence it supplied on the biggest swings. As we’ve found with the best control strings on the market, Revolution’s spin-friendly precision brings the ball down sharply and surgically. Big hitters looking for a firm co-poly with a user-friendly feel will definitely want to give this string a try.
