i just ordered two units of DX009 today and can't wait until i get them and restring them and play with them I bought this over Voltric 9 which I considered for a few days, but for me the all around play of DX009 was decisive, as I don't usually base my game only on smashes and offensive play, although i smash alot actually.
I played today 4 matches in a tournament with it, the string was PolyFibre Explosion B8 @ 27-29... I can say i liked it more than my NanoSpeed 7700. It is very good for net play control, and the smashes seem to be precise and well-controlled. it has a good quality build too, I had a pretty hard crash with my double partner's racket, his racket was broken in the frame immediately but mine easily survived the crash. I can say i like it overall. Although I need more getting used to it.
i bought this racket almost double the price some people bought it for and i would say its a tactical racket very stiff racket and not user friendly. i only use it when i need precise shot. its very good racket but some reason its not a playable racket.
Today I just learned and noted that Yonex Taiwan has provided Arc 009DX with 6 continuous grommets. But it is different mode with AC416 L1/L2/L3/L4 cmiiw
