Specifically the Shimano CX50.

I've been commuting on a 1x9 setup for awhile and I'm building up a new commuter with a 2x10 drivetrain. Right now I have a 38 tooth front chainring and a 12-27 cassette, which works fine. But I feel limited on descents or flats. The 36/46 setup seems like a great happy medium. Just wondering if anyone has tried it and can comment on its functionality and shifting performance. Obviously I don't think it would suck...but I want it to be wonderful.
