I recently had a bike fitter lower the nose of my saddle in an attempt to make it level. I was constantly sliding forward on it, and when I slid back where I should be, had 2 pressure points under my sit bones. Then I tipped the nose back up slightly to where I stayed put on the saddle, and I no longer had 2 pressure points under my sit bones, but was supported over a much wider region of my pelvis by the outer rear third of the saddle. Now very comfortable again. So guess I'm agreeing with SK on this.
