This is the MIZUNO ALTIUS 01 feel. The strings are EXBOLT65, strung at 25x27 lbs. It's very easy to use. All shots are easy to hit, and there's no play you can't do. For singles, it's suitable for all-rounders. For doubles, it's suited for skillful backcourt players. I think this racket is ideal for those who prefer to control the game with control rather than power, and who can score points with well-aimed shots. I recommend it to beginners, and also to those who want to control the game and improve the level of all their shots, regardless of their skill level. Please consider purchasing it.
