Shimano recommends STi 8 shifters on seven drive trains,
having dropped seven STi levers. As Chalo notes, in
practice they are only negligibly askew. If you set the
index in the center sprocket the variance at both extremes
is not discernible.

That's exactly what I do and what I said upthread. Another type of shifter that's getting harder and harder to get is one with a friction mode setting as well as index.
