A way to lose height whilst travelling straight down the Fall Line of the slope. With both skis pointing across the Fall Line and the edges engaged, the Edge Angle is reduced by tipping the edges downwards. This will start a controlled side slip, which can then be stopped by re-engaging the edges with the snow.
