On my Trek 720 I went from friction barcons and a 5 speed Helicomatic (sometimes Phil Wood + Suntour Ultra 6 depending on wheels) to a 10 speed Phil Wood/Ultegra with Command Shifters.
It's great stuff - getting all those extra steps between gears.
I guess if you don't go the Brifter route- the 9 speed bar ends are still available. As far as what bike... I love the concept of *my bike* with this new fangled stuff on it.
And here you go:
Retro roadies- old frames with STI's or Ergos
