The following link is to the Shimano site, but the sources mentioned above will give you the same information. The Shimano site does not seem to working tonight, but you can click on Tech Support and then Tech Documents and the y will have the specifics for the Tiagra FD.

I followed the same instructions Panthers007 pointed out, particularly the Bicycle Tutor. I get to the point where both the H and L setting are correct and the I shift down to the highest gears in both front and back and set the cable tension. I move the shifter to the lowest gear position ( I assume this means where it would shift to the big ring....) and tighten.
I think it finally comes down to what you both suggest... cable tension needs to be set precisely. I've used the barrel adjuster on the Volpe, but maybe I can have a brief interlude of tweaking it before I let the adjuster nut off (and then need a new cable
)
I guess this need to micro-adjust the tension is what's missing. But I still think these brifters are at least part of the cause. I've adjusted triples with friction shifters and it seemed much easier.
I'll check out the link you provided too... although right now it just bring me to a picture of Denis Menchov (who has no problem shifting at all..
)
