I run a 50/34, 12-27 setup myself.

As for a 11t cog, I rarely find myself really missing it. Sure, it would be nice. (If they would come out with a 12-speed setup with a 11-17 straight block followed by 19, 21, 23, 25, 27, I'd be very tempted.) But I can still pedal smoothly past 40 MPH. By that point, I'm usually not pedaling and just tucking anyway.

The one time I missed it, I was drafting off of an SUV when we hit a straight 7% grade downhill section coming out of a turn. I pedaled up to 44.6 MPH but then didn't have the legs to spin much past 140 RPM to keep in the draft. My best short bursts of speed tend to come around 120-130 RPM, so perhaps with another gear, I could have kept up for another few MPH speed gain. But whatever... I wouldn't have broken my top speed record anyway.
