I have the pure drive with cortex and i was wondering if it is necessary to use some sort of damper. im not real worried about my arm but i dont want any damage to it and sometimes it hurts. would a damper help that?
once you get good at stringing you will be able to take more time on your rackets and make sure that they are strung just the way you want. sometimes proshops have a lot of racquets to string so they use techniques that may be faster but not as good for your string. my friend said something...
