I read an interview with Federico Bahamontes a couple of years ago where he complained that index gearing made climbing too easy. His argument was that friction shifters didn't allow you to drop a cog when someone attached; you had to respond in the gear you were in, as if you were dicking about with the levers you'd get dropped.
