@opustennis: We ranked every number on the spec sheet by one question: how much should it change which racket you buy? The weight on the box tells you how heavy a racket is, not how hard it is to swing. That's why two 300g frames can feel like different rackets. Stiffness sits lower than most people expect, because one RA number says far less about comfort than strings and tension do. The further down the list you go, the less any single number means on its own. Which spec do you check first when you pick up a racket? Not sure which numbers fit your game? Take the racket fit test in our bio. #racket #racquet #tennisracket #racketspecs #swingweight
