Interesting,.. I watch a lot of skiing video and Nate, Freddy, Regina, TW, on and on do not have straight legs. In fact they drop their hips overtly. There are a couple of styles out there and the straight up and down knees straight does not work for me. @kfennell JimBrake made the statement that helped me re think this 'falling away is putting the brakes on while trying to accelerate'
@ozski the rope is forming a line from my ankles/hips/and shoulders shooting for what TW would coach me to do!
