I have a 22/32/44 on a road bike; however, I also could also have chosen 24/34/48 right off the shelf if I'd wanted a little higher gear (48x12). With this, I have Ultegra index shifting using the new 12x27 DA 10-spd hub.
I had the complex, down tube, double shifting arrangement that you're talking about on my old-old "15-speed" to get the most usable gears out of it as I could at the time. However, I didn't have nearly as many usable (for me), closely stepped gears and easily shifted gears as I have now.
For example, I now have about 17 gears starting below 1:1 with a step of less than about 14" between gears without any double shifting (except with each single change of the rings when going from low to high).
