I think those old Japanese derailleurs worked better after they'd broken in, just like the Campys. The Cyclones were a really nice shifting derailleur once it got a little slop in it, didn't seem to need to be fine tuned as much. The VGT derailleur just seemed to be slow shifting. I just didn't like 'em, a good cheap replacement for simplex, nothing more. Of course the Campy's took quite a bit longer to break in. A couple of mine are just getting broken in! And they're only about 20-30 years old. When it comes to the nice old racing bikes, I've just got Campy (except for the headsets) on my mind.

<<<I'd be curious to hear about the movement in millimeters (using the above
test) on these older Japanese derailleurs with all the miles on them. My well
used Campagnolos have about 2 to 3mm movement. 2 at the upper end, 3 at the
lower.
