The saddle is heavy, expensive, and requires care. I find it very comfortable though, and when sitting on it or 8 hours, that's all that matters.
A hear that a lot of people find them uncomfortable until they are broken in. Mine was pretty comfortable right out of the box. I am a light weight rider, perhaps that is the difference.
It did take me a little while to adjust it to where I like it. a few millimetres up/down or back/forward can make a HUGE difference.
After a long ride I will feel it, but not to the point that it is distracting or painful, and I'm always ready to hop back on it the following day. I wouldn't trade this saddle for anything.
