Sounds like the Ultimate King saddle would put you a inch back and a little higher from what others have posted here.Plus they give you 14 days to try it and all it costs is shipping back if you decide to return it.I'm 6'5" and that is what I am going to get next year when funds are avaliable.I installed the Kury mini boards which put your feet down a inch lower and can be adjusted foward and tilted.they helped me in extending the legs a little.Only other seat I can think of that would be custom made is the Day Long saddle-I know one rider here has his 4" back as he is a big boy too like me.
