A popular hybrid combination, Babolat Pro Hurricane Tour + Xcel combines the durability and spin of the stiffer co-polyester string with the enhanced feel and comfort from the much softer multifilament string. Typically used in the main strings for its durability characteristics, Pro Hurricane Tour features an octagonal profile, allowing for greater spin generation. The Xcel is often used in the crosses to increase the feel of the stringbed and decrease the overall stiffness. This makes an otherwise stiff string like Pro Hurricane Tour accessible to a broader range of players. The hybrid combination is best suited to advanced players seeking durability and spin, but with a softer feel. The thinner diameter of the polyester string in this hybrid allows for greater spin potential with slightly reduced durability.Construction: Extruded Co-Polyester / Multifilament Polyamide Color: Yellow / Natural Gauge: 17 g / 1.25mm | 16 g / 1.30mm Features: -Control and Power -Xcel slick PU coating -Hurricane Tour 8-sided for more spin
