Buy one of the $100 dollar AirHawks and you'll be laughing and riding all day painlessly.
The "comfort" seat is stepped and locks you into one position and offers no decent ventilation properties.
Have one fitted to my bike, makes a huge difference! I would consider getting an airhawk, only reason being is that you can take that with you and fit it with whatever bike you have!
I'm about to chuck a sargent seat on ebay. I recently bought one but it doesn't work for me. I'm 5'9" with short legs and the sargant seat puts the seat height up to the normal F800 seat height (I use a low seat usually ). That and it seems to push me further back and so more weight goes on my wrists as I have to lean forwards. Also, my missus doesn't like it. She says it is more comfortable on her arse but pushes her up a bit which makes holding the grab rails a little more tiring.
It is softer on the arse and if I was 6' tall it would have been perfect for me even if not the missus.
Try before you buy or it is an expensive lesson to learn !
