For what it's worth, I have silver shifters and a Shimano 12-27 cassette on my Sam, and it shifts exceedingly well. Because of it I have fallen in love with friction shifting, and have turned off the indexing on my Fisher monster cross (Shimano 9 speed barcons, custom 12-32 cassette). On the Fisher, I regularly get unintentional shifts, especially in the big cogs. Both cassettes are reasonably new, both chains are reasonably new SRAM. Haven't swapped things around to isolate the culprit, but my suspicion is that the Shimano shifter in friction can't be adjusted in similarly small increments.
