I've been using this seat for a few month now and as the others have said it is the most comfortable. In addition, it seems to be exceptionally durable compared to any seat I've ever had on any bike. They are expensive but they will last you a lot longer than any other seat I've seen.
This is hands down the best seat I've ever used. so comfy right out of the box. I ordered the complete seat for $105 more and it was worth every penny. It is a little pricey for complete seat but the quality is outstanding and you really get what you pay for.
