Hello,

I'm currently running early "pointy" style 8 speed Ergo shifters,
an older style (tension adjuster on the back) 9 speed compatible
Campy rear derailleur, and 8 speed Shimano cassette hubs with a
Campy-compatibility spacer kit.

snip)
Something to think about is what is your generation of Campy 9-speed rear
derailleur. If it is post-2000, then it has the new mechanical advantage of
1.50 to 1. If you match this with a old 9-speed index ring (pre-2001), you
will get derailleur travel that will more closely match Shimano 8-speed
spacing (4.8mm) than Shimano 9-speed. If you want to make this work, an
older Campagnolo derailleur is definitely better.

See:

BTW: I have Campy 8 and 9 speed systems. For the minimal benefit of another
gear, I don't think the "upgrade" would be worth the effort.
