Friction shifting is good. With decent equipment, it works just fine. I do like the clean look of DT shifters. And it is not a bad thing for everyone to have some experience with it - kind of like knowing how to drive a stick makes one better able to use an automatic to best advantage.

But properly set up Ergo is better. I want to shift, not think about shifting. And I like Ergo over STI because I want to be able to trim the FD.

The one place I'll sort of disagree is on a fully loaded touring bike. For that, I want Shimano barcons that can be set either to indexed or friction. I can still shift with both hands on the bar (with 40+ lbs of gear on board, there are times when this is a very good, even crash-preventing, thing) and if somethng goes hinkey with the indexing for whatever reason, I can still keep going. And because it's Shimano, odds are good that I can get parts at a small-town bike shop.

Otherwise, it's Campy Ergo FTW.
