Not sure if this makes any difference but I'm also using a dura-ace rear mech. Was after lightweight and really like the action of them together. Really really crisp and smooth - enjoy changing gears for the sake of it now...!
I'm using Pauls thumbies on my mod bike (Pace 303) on a riser bar with 9-speed Dura-ace barcon levers and a Sachs Quarz rear mech (the original polished alloy model). Works fine.
Everyone thinks I'm mad though.
