wow dan, isn't that a new thread?
My wife loves the mustang pillion. Can't speak for the other seats as all I've had is the mustang and stock. She hated the stock pillion. I'm so used to my mustang that my back hurts on my R* when I put the stock back on. My butt hurts me with the mustang though quicker than the stock did and it is easier to squirm around and find a semi-sweet spot on the stock seat (at least for 30 seconds
). Got the mustang for three reasons... nicer pillion, back rest for me, and I liked the looks.
