I just got back from my test ride...
I actually really like the shifters. They are wonderfully smooth and as easy to operate as indexed bar cons. My hesitation is that reaching for them isn't as comfortable as I would like. I'm sure this will improve with time but it gives me doubts. I also got to try out the Tektro 340's. They aren't much to look at but functionally offer some pretty great braking action from the hoods.
I'm still really torn about everything. In an ideal world I would be running campy ergos on this bike. I plan to commute, light tour and do some randonneuring on this bike so I want the components to be nice...just not too nice.
