Its certainly less predictable now and it was also less predictable before the era you speak of...at least I think it was. Its hard as my tour teeth were cut between 1984-1990 so that is always my eternal sunshine time, I'm not objective about it. The EPO years were full of sledgehammering the shit out of the GC but I recall there were still battles along the way, they were just overshadowed by ridiculous wins that didn't seem possible.
I have had a few ales; heres Lemond, Hinault, Roche, Delgado, Parra, Herrera, Winnen knocking lumps outta each other. Note the conspicuous lack of trains, team mates (Hererra excepted) and measuring effort. When riders go they really do GO. None of the jerseys are shit, the bikes look mint and the lack of helmets and shades mean you can instantly tell who is who. Jumpers for goalposts.
