I don't think there is any reason to fly either fast and low, or steep and slow. Just fly the same approach you would with a heavily loaded single: steady deceleration with moderate approach angle and a loaded disk. GOM Longranger style. My call would be that you are introducing far more risk with the first two approaches than you would ever gain for that statistically improbable engine failure at a critical time. Look at where the problems are and engine failures at CDP isn't one of them.
