I bought the Kore saddle because the West biking failed after, let´s say, 1500km, so very few km in good road conditions and my 74kg ass. It broke not on the rails, but on the seat plastic structure (there is a pic of that with the ironic QCpassed sticker).
I chose the Kore because I have the wheels and everybody likes them, so I gave it a shot.
Here are a few pics comparing both models.
Hope it lasts more than the West Biking.
They are in the same US60 price range, depending on offers.
