I have a N90-II just boguht about 5-6 weeks ago its new ( it has 2 tiny chips due to framing tho , i dont play doubles so no clash). Strung with nanogy 95 25lbs, this racket is too stiff for me, i can't smash properly. I want to trade this racket for a z force, preferably ltd. i would pay a little extra to compensate. And i would let this racket go for $170 Inbox me if youre interested
