No one can tell you what seat you will like.
I have been through Stock, Stock with Utopia Backrest installed, Mustang, Ultimate with backrest installed and Corbin Dual Tour with backrest installed.
I would have kept the Mustang IF it had an available Backrest, but it didn't. I am more that happy with my Corbin. Good quality and comfortable for me for for long rides (400 to 500 mile days).
Although if you buy one and do not like it you CAN NOT return it.
