Offering a high level of control and a softer feel than traditional polyester strings, Co.-Focus makes a great choice for big hitting players looking for control and durability. We found excellent access to spin when testing this string. Comfort was also impressive for a co-poly and we found impressive performance at a variety of tensions.
