Scratching on DJM2000

Hi all, so i'm in the market for a new mixer and have been agonizing between the 900 and 2000(hope i'm right). I narrowed it down to the 2000 mainly for the touch screen midi controls for use in ableton live. However, I also have a pair of CDJ2000's and a DJM909 as I am also a keen turntablist. I will be looking to sell the 909 but I am wanting to know just how tight the fader curve is on the 2000? I can scratch perfectly fine on the 800 and just want to know if the 2000 uses the same curve parameters as the 800/900. Thankyou
