Have the Corbin 2up touring saddle on ours. Great seat. We were living only an hour away from the Corbin factory in California at the time so we went there and had them custom make it for us. I have a broken tailbone so they played with the foam, cutting some out to relieve the pressure in that area, thinned out the nose area little more, moved the driver backrest mount forward about an inch, and put red flame stitching on all the leather. Looks and rides great. Well worth the money in my opinion.
I do wish it had the separate controls for heat like the stock seat had, cause the wife seems to like it a little hotter than my butt prefers. But at least I can sit on this seat for hours unlike the stock seat which forced me to get off after less than an hour.
The Corbin is a hard seat but I believe they are right regarding hard is better than soft for long ride comfort. I have had soft seats, even before my tailbone got broke, and they always gave me "hotspots" after a few hours. The Corbin does not do that, at least for me
