I had looked at corbin as well, but nothing comes close to how slim the L&M seat is. I'm may hit up the guy in your link. I had seen his post before but forgot about it.
I emailed him and cant get a response.StrykenShane said:http://www.yamahastarstryker.com/index.php/topic,15.0.html
i talked to this guy last week and he sounds pretty reasonable on price, I've decided to wait and see what Corbin has to offer.
