Not taking into consideration the things that make Campy Campy and Shimano Shimano (hood size, Campy rebuildability) Chorus weighs 2050 gms for the group while DA weights 2060. Since Chorus is usually "last years" Record, it's full of trickle down from Campy's top group. As you pointed out DA has remain unchanged for some time now. So what exactly makes DA better than Chorus? Having owned both as well as record, I don't see it. That said, Shimano has its loyalist as does Campy but when you compare the two groups and their performance one being better than the other just doesn't pan out. But I'm really open to hearing one way or the other.

JR:
My original statement that Chorus is between Ultegra and DA was based on the 06 groups, to be honest, I forgot about Ultra Torque cranks. That was the big difference between Shimano and Campy. As far as performance goes that was Shimano's only advantage.
There is no way you can say one group beats another based on a 10 gram weight advantage. I ride Campy, but look what DA gives you for an extra 10 grams, an alloy crank and dual pivot brakes front & rear. IMO, aluminum cranks are less failure prone than carbon. Plus, I would rather have dual pivot brakes front & rear. That's why I chose Centaur. It was the last all alloy group Campy made. Unfortunatley, Campy had to spread the carbon cancer down to Centaur.
The above explanation was a personal rant/explanation. It should be taken with a grain of salt.
