I got my racket strung at sports authority. And I was preety angry. When i saw my racket, the strings were NOT straight at all. And looked like they got played. And the tension didnt seem right. But then i new that it must have lost the 10% tension like they say. then i put on the wilson shop dampener the one that goes between two strings, and string savers. So it must have added 2 to 3 pounds. And then i hit the ball with it, i got a PING sound. A preety strong PING. And the last string was NXT and i never got a PING sound as this. So my question - Is this good, bad, the stringing right or wrong, is a PING good or bad? Any thing else i should be concerned. I use a Wilson N-code W4. And no damage to the frame. PLEASE HELP ME. I AM VERY CONCERNED. AND THANKS IN ADVANCE. PLEASE HELP ME GUYS.
