Thought I would answer my own question.
I purchased this saddle and put it on my new Norco.
It is just about the right blend of comfort yet not bulky so it's not in the way.
So far I like it a lot. It's not as plush as the GiddyUp I was riding but suits single track riding much better.
I can slide off the back of it really easy, when I hit the dropper post its completely out of the way. It provides just enough cushion for 12 mile rides! Also with the cutouts and no nose there is no really pressure on the tender bits.
I'm keeping it and the more I ride it the more I like it.
