Had one for a couple of years. Quite firm and you sit slighly further back because of the shape. Very well made made and very comfortable if you like a firm saddle.
Still got one bud and love it. It has the advantage of allowing you to slide back to change position on them long motorway treks and stretch ones legs plus if you do off road it will have obvious advantages. I find it a lot more comfortable in general too but I think you should bare in mind that seats etc are a personal thing and although I love it you may hand over a lot of hard earned wonga and find you hate it
Hope this helps,
Chris.
