Just my opinion, but I fix up a lot of cheaper donated bikes for a couple local charities and I have seen many twist grip shifter thrown in the garbage.
I think your claim of 5mm c-c cog spacing for SunTour cog sets is not correct. Perhaps for the more current ST stuff that does mimic Shimano's lead. But the ST stuff from the 1990s had cog spacing that varied across the cog set. Andy
