Well, maybe the 9-speed chain is the way to go....
According to Frank Berto and Shimano the HG cog tooth profiling (with chiseled outer tops and specific shift gating) was the shift (bad pun) to minimal over shift need and in some cases under shifting realities. For the alternatives the twist tooth (UG) design was far better a shift performance, SunTour and Campy (and Mailard/Huret/Simplex) were years behind. My experience bears this out, although I remained in the past with my SunTour then Mailard stuff... Andy
