The steeper it is, the more aggressive you have to be with your riding. When initiating your turn, project yourself over the nose of the board to get your weight over your front foot. Initiating your new edge earlier in the turn will help you with speed control. The earlier you initiate your new edge before the fall-line the better off you will be. Good pressure control is going to help you slow down between the turns so make sure that you unweight the board before you start your turn and then really sink down on the new edge at the end of your turn.
