I've used the 9-speed Ultegra/Dura Ace, and have never been happy with them, and things like shifter covers are almost impossible to source.
I'm not sure about the 10-speed Dura Ace 7800 series. But, personally I'd go for a more modern groupset.
So, probably I'd choose the 5700 groupset.
Possibly even the 4700 Tiagra shifters. HOWEVER, keep in mind that the 4700 shifters take the 11-speed rear derailleur (4700, 5800, 6800, 8000, etc).
Which shifters have side cable routing, and which shifters have aero routing? I find I dislike the side cable routing.
