What model Goldwing? What are your basic physical sizes? What is your most common riding style? What about the current seat don't you like?
One reason there is so many different options is how each of use rides and what we like.
I had Mustang seats on two different bikes, both with rider backrests and I didn't care much for either one.
I had two Ultimate seats on two different bikes and like them both very much.
I had one Hartco and never took a liking to it.
We are all willing to share experiences and recommendations but in the end you're really going to need to try them.
