I like STI. Maybe I shift too much, but being able to brake and shift all from the same hand positions, and being able to grab that hand position instinctively, is an advancement in bike technology that I appreciate.
My tourer has downtube braze-ons, and I have a right downtube friction shifter that I carry in the tool bag for emergencies.
