Rolls takes the honours, but I'm not sure if the reasoning is sound...
I ride either one of a pair of old fixed beaters to work and back every day (25 hilly miles round trip). One (the 'dry' bike) has a Turbo Special on it and this one sees most action. The other (the 'wet' bike) has a Turbo Bernard Hinault edition on it. Both of these saddles give me butt-ache, as does the standard Turbo gracing my winter training steed (a 70s Dawes Galaxy).
My most ridden road bike, used for anything and everything (except commuting or in the wet), is an early 90s Ribble 653 topped by a textured leather Rolls. This has never ever given me any trouble, whether on a Wednesday evening training run or doing the Coast to Coast in a day.
Perhaps it's time to change my work and winter saddles over to Rolls?
