I have two seats for mine - the standard one which is fine for everyday (and for trackdays 'cos you can slide off the side of it to hang off a little easier). I also have a Corbin seat which seems very firm at first but is nicely shaped anatomically speaking and very comfy on a long haul. Pillions also prefer it because it's got a nice shape that stops them from sliding forward so easily when the brakes go on.
As for the rest of it, ditto what Rushjob said.
Incidentally, the Corbin seat is available for hire to anyone going on a bit of a tour. As long as I don't need it at the same time your welcome to borrow it for the price of a good bottle of Italy's finest red. You need to swap the seat catch over onto the Corbin from the standard seat, but it's a 30 second twiddle with a 4mm allen key to do that.
