Srsly, looking good. The old "High Oxygen/Low Copper Content Interconnect" has doomed many an endeavor. I was sweating because my LBS asked me to bring my charger over during build as Di2 wasn't showing any sign of life (I'd charged it and updated firmware before handing stuff over)....plugged it in and nothing....turned out the mounted battery's cable wasn't quite firmly seated.
