I used my wide range double as a single with a bailout; with 9 cogs for the 44, 9/10 of what I needed required only rear shifts. And, I set up the outer and the cogset for a pretty straight chainline in the cruising gears. With nine or 10 cogs in back, one ring is plenty for everything except loaded touring (I imagine) and steep off road climbs; after all, a 46X32 with a typical 700c wheel gives a 39" low.
