Standard doubles are definitely more popular with racers, but this is demonstrably untrue. Plenty of racers out there with compacts. Or so I believe; I couldn't tell you for sure, cause here's the truth: racers, in general, just don't give a crap about what kind of crank you're running.

Thumbs up for the 46 big ring. My commuter and cross bikes are 46-36 and 46-38 respectively (130 BCD crank on the cross bike). That's a nice size for a big ring!
