I have three seats for my '07 Fatboy. A brawler that looks cool but not so comfortable. I also have a Mustang 17.5" that is very comfortable for maybe 200-300 miles. But for all day in the saddle I use my stock seat with a Firehouse backrest. Very comfortable!
Mustang with backrest all the way!!! Worth every penny, and then some.
+1 on the Mustang with drivers backrest. I have the 17.5" Wide Vintage Solo w/driver's backrest, along with the 14" rear recessed passenger seat for the wife, on my '08 Heritage. I love it, so does she. No complaints.
I have the stock seat as a solo with firehouse customs backrest. Just went 1800 miles riding North and south Carolina, Georgia, Fla and Tennesee. No problem with the stocker and turned 20k this week!!!
