I agree; I don't see the point of two rings on a ss/fixed (so called) unless you want more than two ratios or if you want really big gaps, say a high range for pavement and a low range for off road, with small axle movement. You get a lot more variation for each tooth by increasing or decreasing the number of teeth on the cogs than on the rings.
Me, I'd rather fret about whether I need to change the cogs on my Riv now that I've installed the Kojaks with a diameter of 25" in place of the Turbos with a diameter of 24", giving me a 72" gear instead of a 69" gear (46X16 on the cruise side). I could swap out the 16 for a 17, for a 68" gear, but then would the drop to the flip side cog, an 18, be big enough? I'd have to change that, too, to a 19. Or, I could change the 46 to a 44, but I have far many more 46s than 44s, and what happens in that purely theoretical future when I have racked up so many miles that I have worn the teeth on my two or three 44s to mere nubbins? Fret, fret, fret. Let's see what other artificial problems I can cause myself. Seriously, I am not fretting, but the moral is that a 2 tooth gap in the rear, from 16 to 18 as above, will give you a 8 gi difference (72 to 64) while two on the ring -- 46 to 44 -- will give you only a 4 gi difference 72 to 68) (that's how half stepping was invented, no?.
