I scavenged the Sam Hill Silvers when I built my Fargo and found this: They are not as precise as Simplex Retrofriction, but more precise than SunTour Power Ratchets.
I attribute this to the small barrels of the Simplexes, versus the larger barrels of the Silvers and STs, and longer levers of the Silvers. I lost a plastic washer bit from the right shifter and it does not seem to make any difference. They worked perfectly with the "low normal" LX that I replaced with an 8-sp era XT, with which latter they seemed to work horribly with a bastard 7 sp cassette built out of various 9, 8 and 7 sp cogs and spacers; there were a few cogs that would rattle no matter how I placed the right shifter. BUT: Once I decided not to "rush" the shifts and to wait for the ramps, all seems well. The XT does not shift as perfectly unctuously and esquisitely as did the newer LX, but it shifts well enough.
