My Z force 2 LD version just arrived to my house, ordered from mybadmintonstore strung at 26lbs. However the head of this racket is not the same as the normal Z force 2. The head is slightly shorter than the original z force 2 i compared it with and it is also wider. Is there anything i can do with this faulty racket head? Pretty sure it cant be the racket like that as its just a re painting of the z force2?
