I'm running a 44/30 on a 94mm bolt circle with an 11-28 9 speed cassette and it's spectacular. I can cruise easily at 20kph in the middle of the cogset on the 30. I can cruise quickly at 20mph in the middle of the cogset on the 44. My highest gear is a 44-11 and I can spin that out on a decent and be right at 40mph, beyond which I always have been happy to coast. I'm going to try 46/29 sometime (I already have the rings), but so far so good. With a double, the chainline allows all 18 combinations to be used, although I still avoid the two extreme crosschain combinations (44-28 and 30-11). 16 totally usable gears with basically zero overlaps. Furthermore, with the Campy compact double front der that Riv sells, my setup miraculously is 99% trim free. It's great treating your front shifting like a switch, instead of gently trying to hit the middle (and, yes, I have a number of bikes with a triple. I know how to shift a triple). On a bike that won't be heavily loaded, I think having 16 usable and well-spaced gears between 28 and 104 gear inches is plenty.
