My Corbin has served me well. 800 mile days, no problem. I am 6'6" 260. The key for me seems to be width and firmness of the foam. The Corbin is both.
I agree with the earlier post, I like to be able to move around. The slick texture and somewhat flat design of the seat allows me the ability to move around in riding pants easily. I prefer that over the bucket feel. To each his own.
