Hi everyone I'm a junior player age 14 .i usually played doubles,rarely singles. I am using victor bs10 and this January I'm planning to get a new racket. I am an aggressive player ,not really good at defense. And I found my current bs10 suites me well. Can anybody help me choose between lining n90ii,n50(first edition),or nanoray 700 fx ,I play doubles more as a front court player. But also likes smashes..
