Further advancing their copolyester products, the Babolat Pro Hurricane Tour offers a number of innovations over previous polyester based strings. The first thing to notice over standard polyesters is that this string is made of different blocks of polyester which are combined and extruded to exhibit unique characters than each makeup would alone. In the case of Pro Hurricane Tour, the result is a string that offers greater flexibility, which makes the string process easier as well as providing additional comfort during play due to increased ball pocketing. This string also holds its tension better than typical polyester strings, again thanks to the combination of properties that is possible with the co-poly construction. The octagonal profile of this string helps to generate additional spin by allowing the strings to bite the ball more during the additional pocketing. Pro Hurricane Touralso features a silicone coating, which helps durability by lessening friction as the strings move across each other during play. All of these features combine to create a string fit for the heavy spin, power baseliner of today's game. Recommended for strong players seeking durability and spin, with a touch of extra comfort.
