a friend of mine had a Arc-Z that he hated. he hated it so much he hates using it and was planning to sell it. i gave it a look and whoever strung it was on some kind of drugs. the tension is so low (even when claimed 24lbs) and the top cross was wrapped in some really strange way. i told him that it is probably the fault of the stringjob so he had me restrung it for him. now he says his Arc-Z went from being his most dislike racket to his favorite racket. just because i strung it for him properly. that was a good compliment.
that's what we're here for... but seriously, sometimes we take for granted the excellent stringjobs that our regular stringer provides us and choice of string, tension, and proper installation is just as important as choice of racket, much like how the choice of tires and pressure is important to the handling of a sports car
