This just came up on the facebook forum also. My opinion is there is no objective answer. What works for one may not work for another. Seat brands that perform well for one rider on one bike may not provide the same results for another. My Corbin is very good. I find it to be comfortable for hours on end. The Corbin also resulted in an ergonomics change for me that was beneficial. My wife wants a Corbin for her CTX700. It has much thicker foam, raises the seat height, and certainly changes the ergos. So Corbin may or may not be the right seat for her. It is a difficult and expensive venture. I am 602 240 and the Corbin performs flawlessly for me. I am very happy with the decision to purchase. But, most owners generally seem to be happy with each unique brand of aftermarket seat. Very rare that you see a complaint about any brand, but you can always find legitimate criticism of any brand.
