how often do you have to get your racquet restrung? i mean im pretty pissed off lol, first of all i bought my racquet about a year ago.. and just a week ago or so a string finally broke. so i got it restrung and it cost $35 (aussie money) which is i think like 25 US dollars... i got kevlar strings, which were supposed to last longer.. as quoted by my restringer "more durable" and then after playing tennis 4 times, my strings broke again, and it was the same string again. (not blaming him, but hopefully will get a refund) i was really pissed off, i was playing pretty good, and was having tons of fun, then i went in for a backhand slice, and i hear a sound and im like "omfg, not again!" so have any of you had an experience like that ie. u get your racquet restrung then they break a few days later?
