A lot of people say the Corbin FZ6 seat is too slippery and angles too steeply from the back. They make great cruiser seats but it does not look as if they have got the FZ6 right yet. I cannot say from personal experience as I have the lowered FZ6 seat....don`t ask you cannot get it in the USA and it is too expensive to import from Europe.
Bagster makes a great looking FZ6 seat and I have only heard good things about it.
Open the link and put the year of your bike in and then click on Make your own seat. The rest is obvious.
