Hi, I am new here and just purchased a 07' FXSTB Night Train. Love the bike, hate the seat. I have been looking around at seats and can't decide between the Saddlemen Explorer or the HD Sundowner. They look almost identical. I know the Saddlemen has some sort of gel but other than that I don't see difference. I am getting awful tailbone pain after 40 miles or so and want a seat to help with that. I have both stock and sundowner for my V-Rod and the sundowner for it is ok but not great. Anyone know what seat would be better? Thanks for your help.
