Well, no one can really tell you which seat is going to work for your butt. You may try hooking up with some local riders who have different seats, and see what they feel like...especially if they'll let you ride around for a few miles. I have a Corbin seat with backrest and have put literally tens of thousands of miles on it, and I love it. I tried the Mustang and did not like the way it felt, but I did keep the Mustang pillion and mated it up to the Corbin for either my wife or daughter to use when needed.
