Corbin, check out their website, they have passenger seats and backrests too. I've had them on several bikes and think they're the best. I had a gel seat, the Corbin is so much more comfortable. Like all seats they take a while to break in, but they really mold to fit you. They will also shave them down when you order if you want to sit a little lower. You can get them in several colors(not all shown on the website) and if you get the carbon pattern on top, it has some grip to keep you from sliding. Also you can get them without the piping(the trim that seperates the top and side material) as this can cut into your legs. And you don't have to send in your seat.
Some folks like the Tobin seats too, they're good, but not for everyone. As you can't slide all the way back in the seat due to the hump where they cut the front of the seat down.
