I just got back to real life after a ~2000 mile trip. My stock seat had undergone a Spencer seat mod which as I understand it is mostly a re-foaming. Some forum members find this to be enough of a change, I did not. My tail bone got pretty sore after consecutive days in the saddle. I put an Airhawk inflatable seat cover on; That helped a bit, but the tail bone still was sore.
I am currently saving up for a Russel day-long saddle with back rest (
day long saddles). The majority of people on this forum want to preserve the sporty look of their bikes, and that's where saddles like the Corbin come in. If you, like me, truly do not give a damn what your saddle looks like, then the Russel is probably the answer. At Barber vintage motorsports museum they have a few world-record long haul touring bikes on display that were all the actual machines used. They all had dished saddles similar to what you will see out of a Russel. Again I haven't tried it yet, but by all appearances if you want a saddle for all day comfort something like the Russel is what you want.
Others will likely have better suggestions if you are more concerned about appearances.
