Wife and I are planning a 30 day 8-10k mile tour of the western states for the summer of 2016. I know that is several months away, but I want some time to test/prove/improve any modifications I make on the bike long before we set out. We are riding an '07 Ultra and will be towing a trailer. I am looking for any general advice, but specifically looking for recommendations regarding seat choice. I ran the stock seat for about 70,000 miles and then installed a Mustang seat. The Mustang seat now has 70,000+ on it. I am considering the Mean City Cycles or the Astech seat mods. Thoughts?
