What are the real differences in the Campy chains? Veloce vs Chorus vs Record, besides weight. I've got a line on them and there is about a $5 difference between each one. These are the 5.9 chains.

I doubt there's any difference in longevity. It appears that the Record model has hollow pins and lightened side plates, Chorus only has the lightened plates and Veloce has neither.

Get the Veloce, I would bet performance (?), strength and longevity are very very close if not identical.
