Because the Modolo Morphos brifters have different settings for cable pull (5 to 9 speed campy and shimano), I wonder if they might be useful setting up a bike with drop bars and an internal hub.

Maybe not something like an 8-speed hub, but at least a 3-speed hub? Is it true that '3-speed hubs don't need super-accurate shifting as long as 2nd gear is correctly adjusted'? In that case, anything that moves the cable in each direction might do the trick.

Has anyone had any experiences with something like this?

I have a set of Morphoses. They are pretty annoying with derailleurs, so I'm tempted to experiment with them.
