Hmmm...so many choices... I might be in the same boat as TMK, though, if the Mustang pushes you that far forward...I'm 6'2", 240 lbs., although my legs aren't all that long. And I'm with you,
Map, on the back support...I've got 2 lower back surgeries under my belt (pun intended

)over the past 20 years and have had 2 discs removed, so the back gets sore really easily. Back support is key for me, and the stock seat just isn't gonna do it unless I add something like the Custom World adjustable driver backrest that moves forward, tilts, blah blah blah.
Pop, I really like the way that Corbin seat looks...that's the one marketed by Yamaha? Do they sell the model with the driver backrest? I wonder if Corbin sells the same seat cheaper under their own name minus the Yamaha trappings. I think I need to check out the Corbin web site.
Sharp R*, Pop...are those AZ plates? I moved here from there...still trying to sell my house in Surprise. Wanna buy it?
Thaks,
