I have not skied on a KD since 2003 so I am by no means an expert on it. I will e-mail Gordon Rathburn who runs Ski Paradise down in Acapulco and ask him this question for you. He gets KD's and D3's among other skis down there to test each season and has a good grasp on what is performing well. How tall are you and what do you weight? I was skiing on a D3 69 and recently moved to a 71 and did not lose any perfomance with the new technology they have out there.
