When coached by Mapple, Chet, and K. Lapoint, they all asked me my PB?After I answered, each one responded almost identically, "Ok, what's your PB behind ZO?" All three of them explained how a bigger skier is disadvantaged by ZO, and spent most the session helping me "trick the system" ZO shouldn't pander to fat asses, but it seems like there is room to improve!
