I currently have Liberator X saddles on 2 of my bikes. I have very wide sit bones so there aren't a lot of options for me (my road bike came with a Terry butterfly that was way too narrow). Overall, I like the saddle. However, even with the wider rear platform, my sit bones are still on the edge- I therefore switched my road bike to a Brooks Finesse- it's a much better shape for me, though a little on the hard side. I still have the liberator on my tri bike and on my old touring bike. Another issue is that the front part is pretty wide.

So I guess the bottom line is that it's a reasonably good saddle (though not the lightest). For me it's one of the few options available with a rear platform that comes close to being wide enough. If I had narrower sit-bones and money to spend, I opt for something more streamlined and lightweight. Certainly worth giving it a try though.
