Maybe it sounds like a noob question, however, as a tennis player I'd like to know how to differentiate between a "bad" and a "good" string job. Sure, everybody thinks that if a newly strung racket feels "tight", is good, but I'd think there's more to it than just the feeling of a fresh string?! Recently I had some strange experiences. One of my rackets [Volkl DNX] was returned from stringing with almost all grommets cracked. I hit fairly hard, but can't believe that would crack all grommets!? True, can't blame the stringer, didn't look at the grommets before, just wondering if this is specific to this racket brand/model [larger than usual grommets], or is something to do with the strings used [Gossen OG Sheep Micro or Prince Original Synth Gut] ? On another racket, with Prince OSG, broke a string for the first time in more then 10 years! Any input would be appreciated.
