C Ville,
I've had my 2007 M50 for three months and the missus is anxious to ride with me, but hates the stock mini-pad provided. I love the look of your Corbin DT with backrest, but my wife is concerned about back support.
I had originally thought to get a tall Cobra sissy bar and a Mustang seat until I saw your bike. I know Corbin seats are supposed to be more supportive, but has their customer service improved at all over the last two years (most of my "research" indicated they had a good seat but bad service - but most posts are from two years ago)? And where does the backrest hit the passenger - lower back, slightly above, etc.? TIA.
