another interesting solution:
campag 10spd shifters with PRE-2001 geometry campag derailer (ie.: 8 -9 speed ones with the older style cage and b-tension screw design.) Preferably with 11spd chain (no, you don't need to change the jockey wheels, 8-9spd pulleys will work fine)
absolutely noiseless and smooth on shimano-sram cassettes. Impossible to set-up correctly with campag cassettes. (actuation ratio is a bit less, so it's theoretically perfect for. cc 3.97mm spaced cassettes, vastly undershifts on a campag-one)
I know this, because running this combo for more than a year. I swear it works better than a true-all-out 10spd campy setup. And cheaper to maintain. One can get pre-2001 chorus derailers around 20-25EUR if know where to look.

old campy derailer (actuation ratio around 1.4-1.44) with 10 spd campag (roughly 2.8mm cable pull)--> calculated cog pitch in the 3.97-4.05 value. Just perfectly matches sram-shimano cassettes.
