I have a Victor Discovery IV which has marks like followings: tension 7-9.5 kpa flex/power 18 what are the meanings of them? I am new to the board and thanks in advance.
1) Why do you buy a nerd racquet when you are not a nerd? 2) flex/power 18 is some term used to describe the stiffness of the racquet. 3) tension is about 21-29 lb after my interpretation. 4) Just string it at 24-25 lb on the safe side.
