I think proper tuning has a lot to do with it. If they are correctly set up, there is no difference in shifting between centaur, chorus, veloce, record, or even the old mirage. The only difference is material and weight. Now, if you say xenon - yes some of those tended to be sloppy but it was mostly in the rear, and they could be adjusted right in the end, it was just more cumbersom for whatever reason. But between centaur and chorus you should not have seen any differences in shifting. I guess whoever tuned your bikeat the time did not take the time to do that properly, sorry...
