Well, I've read through some threads and it seems the Mustang might be the best bang for the buck. My number one gripe on my last one is the same as this one, the seat hurts my rear and causes me some back pain. Doesn't help I have a broken tailbone. I like the look of the Mustang seat, it's not over done like some. I guess it actually has a built in backrest due to you sitting lower on the bike. The passenger portion looks really well designed as well. Appears to have leg depressions, definitely cool, and it works with the OEM backrest. Any others I should consider? Looks to be about $530. With having to buy a new shield, and most likely two new helmets, gotta set some kind of budget.....
