Your cornering position is the one that will provide you the maximum gain of time. If you manage to completely integrate the movement instinctively, you will be able to throw the bike around in no time with tons of grip.
The straight line position will allow you to have more amplitude with your arm and leg ready to absorb. Look forward will help you to anticipate obstacle and prepare your bike to brake or corner. The main goal is to provide you a position where you feel relax and stable to save energy.
