Kestrel Talon SL 48cm Shifting Poorly

[twalsh]

I wondered if anyone has had shifting problems with the Talon SL. I have the smallest frame size available, 48cm, and everytime I get the bike back from the shop the shifting is suboptimal. The bike looks sweet, but my old bike with 105 shifters is way smoother. Could this be a problem related to both the small frame size and the internal cable routing? Maybe I need a new mechanic?

My Ultegra 9 Right Shifter broke after 3 months on my new bike. Was replaced by Shimano under warranty. I had to ship it to Shimano, Performance Bike did not handle the warranty.

My brand new Dura Ace 9 shifters need braking in - they feel to new.
