I also have 10sp rear on a Campy friction bikes with NR on one and SR on the other. They work great that way and shift much better than the old 6 speed freewheels. The ramps on the cassette make the shifts smooth and the spacing is so tight that you are almost never between gears so it is quiet. No more clang, clang, clang.
