If the OP doesn't want to use Campy for this application (which baffles me, because they're like 10x better than any Shimano brifter) I have a very nice set of 600-Ultegra 6400 tri-color brifters* I'd be willing to part with. However, the front will not shift a triple without some gizmo I've forgotten the name of (but a double like 42/24 is better for touring anyway!
)
*Edit: oops, forgot the cables don't go under the bar wrap on these... Seems like the OP is chasing some imaginary component that doesn't exist.
I second the suggestion of down-tube shifters. All of my drop-bar bikes have slowly migrated to them except for my cyclocross racing bike, where having the shifter within immediate reach is a real advantage.

It isn't the pivot ratio of the der that makes the difference its the pull of the shifters and 9sp sora will pull less.
No. Wrong. The cable pull of the shifter and the pivot ratio work together and DA7400 **is unique**. An 8-speed DA7400 shifter pulls the same amount of cable as any Shimano 9S shifter. So if you use a 9S shifter with a 7400 RD it will shift an 8-speed cassette. Read up on Sheldon Brown's site before you go around "correcting" people with wrong information.
