They're all different, but I'll take two AT900Ps because they're closer to my AT700, and I dont' really like the 9000X or the 99 (dunno why).
absolutely different types, and totally depends on your playing style. How about choose a NS900X, since it is the most expensive one. does it make more sense?
OK. the first two are both even balance, 9000s is head light, well I don't know 9000x. 9000 and MP99 are both extra stiff, but MP 99 is a little bit head heavy, not as heavy as any racket in AT series. Overall, MP and NS both for control player, AT900p is for offensive player.
If you don't know what you like out of these 3, don't buy any because you reallt should not buying these expensive reacuqets. If you are buying for me, I would like to have NS9000-x because it is most expensive and I have 2 already. Want another 1 so I can retire the oldest one.
I would choose the at900p personally. But the choice of racket depends on your style of play and which racket type you feel more comfortable with. I recently switched from an evenly balanced racket to a head heavy racket. I had no choice because my racket broke so i had to borrow my friends at800df which I brought of him in the end. It took some time to get use to a head heavy racket, but once you get use to the timing you can unleash a wrath of terror
