Do Campy shifters jive interchangeably with Shimano derailleurs these days, as far as indexing goes? I can see using Shimano and Campy 9sp cogs interchangeably, but was under the impression that you need either Shimano+Shimano or Campy+Campy when it comes to the rear shifter/derailleur combo, due to differing actuation ratios. That seems to be borne out by Sheldon Brown:
Campagnolo Ergo shifters are rebuildable and upgradeable. They use of different, opposite motions for upshifting and downshifting. This makes them more intuitive in use and reduces the risk of missing a shift. They don't have any free-floating cables to get in the way of your handlebar bag or other accessories.
The front (left) Ergo shifter is not indexed, so it works with any front derailer and any combination of chainring sizes.
The use of Campagnolo shifters requires a Campagnolo rear derailer.
