My, my, we all do feel strongly about our chains.
dkoloko, where can I find that Berto reference? Google fails me.
Yes, in many bike forums "lube wars" are second only to Shimano vs Campy wars in the amount of heat they generate.
As to the Berto reference, I don't know either but Velo News magazine has done guantitative lube tests in the past couple of years and they should be accessible on their webs site: velonews.com And yes, paraffin did win their tests but they were dealing with newly treated chains, not durability.
