I am with the people that say CORBIN - however, I will say it different...
I say it must still fit YOU and that is the trick with any seat... I have a Corbin but it most likley will NOT fit YOU... Why, becuase I am lucky enough to live close to the CA Corbin Factory and I did a ride in appoitment. Meaning I was there at 0800 and met with the seat maker and We worked all day to make the seat fit both me and my wife after WE said - thats perfect - it got covered and we left..
order a seat through the mail is hit/miss at best.
Eventhough I have my Corbin, I still take breaks ever 100 miles or so. Just completed a 7421 mile , 28 state ride and we felt great every night. NO prolbems.
