I guess I'm a Corbin seat person--I've had three. Two came on used FJRs I bought. The first one, I hated. It was like riding on a telephone pole. Sold it and bought a softer and more comfortable Sargent saddle.
Then I got a KLR and after looking at the options, rode to Hollister and had Corbin make me a saddle. Here it is:
After I was satisfied with the shape, he asked me if I wanted stitching in the seat. They'd have put anything on there I wanted, design-wise. The main reason I had them do it was because to have the pattern stand out, they put an extra layer of some kind of material under the leather to give that "quilted" effect, and I thought it might bump up the pillowing factor a little. I still remembered the hardness of that first one on the FJR. This seat was actually VERY comfortable. Those "flames," btw, he just freehanded onto the leather with chalk and a gal stitched them on with a machine. Not too sure how much comfort they really added, though.
By the way, the stitching of the seat is different from the "piping" (in this case gray) around the back edge of the seat and the ridge between the rider and passenger. It's really for looks, and is optional. I like it, myself.
The third Corbin came on my second used FJR, and is MUCH more comfortable than the first one was. I'm keeping it, though I don't truly LOVE it. Still haven't found one I really DO love, and I've tried a lot of the major makers, at least for short rides, or just to sit on. I think Corbin makes a good looking and well made saddle, and they make enough of a variety that you would be wise to evaluate them separately, since there's a big variety of comfort for individual tastes. You don't say where you are in your profile (which you should go back and add), so I don't know if you can get to the factory for custom work. That's the best bet, if it's possible for you. Good luck.
