I agree with Roger. I would be very surprised if you will ever use the low ratio in a two-speed rear end. So what you should be aiming for is the highest (lowest numerical) ratio you can get. In many cases, the single speed axle has a ratio that is pretty close to the high ratio of a 2-speed -- so there's no advantage to switching to a 2-speed.
