I didn't hesitate to spread Capo #1 to 128mm, so that I could use a 7-speed freewheel. (I am currently running it at 126mm with a standard 6-speed.) I think I can avoid spreading Capo #2 by using a SunTour ultra 6-speed. I simply cannot get the range and tight ratio development I want with a traditional 10-speed transmission. I can barely do it with 12, and I can pretty easily get the gears I want with 14, 15, or 18 speeds.
