I've got a Corbin on my '09 Versys. I bought the Corbin because at the time, Sargent wasn't making a seat for the Versys. When I talked to them on the phone they said they weren't going to make one. They said they looked at doing one but couldn't make it fit the lines of the bike so they scrapped the project. Then a year or so later they came out with one for the Versys anyway. I've had both Corbin and Sargent seats on bikes in the past. I prefer Sargent. They seem to be more comfortable (at least to my rear) and they also are much lighter than Corbin seats. Corbin's seat pans are ridiculously heavy.
