Equipment Junkie. You know, you have a perfectly good racket that works really well for you, the blade, the rubbers, everything is good, and then you go out and buy a ZJK Super ZLC with Dignics 05 and 09c and then two weeks after getting that and deciding it is the best setup every you go out and get a CyberShape with H3N and Omega 7Asia and decide it is the best racket ever, and then 2 weeks later you get the Apolonia ZLC with Rasanter R53 and R48 and now that is the best racket ever until you get the Prirmorac Carbon with Dignics 80 T19, and then that is the best racket of all time until you get a Darker Speed 90 with ....... you get the idea.
EJ = compulsion to buy more and more equipment until you have tried every blade and rubber combination ever made.....or, until you go broke trying.
