This board makes such a difference. I demoed it in 2013 then bought the 2014 and it keeps getting better. I have only ridden it 10-15 days due to the thin early season snow we had in SLC. I rode a NS Legacy prior to this board and this board is worlds better. It pushes through skier bumps, kill moguls and jumps up on powder. I would say I am an average rider and this board makes me above average. Does equally well on groomed runs, skied out bowls and powder in the trees.
Never Summer boards are tough and take a beating. I am 6' 2" 230 pounds and don't think twice about rolling over a downed tree. I have heard some hits that make me wince with a new board and the base shows nothing. There is nothing better than checking the base and coming away with a smile.
The carbonium top sheet allows you to be lazy as you don't even worry about your foot coming off the lift. I have never put a stomp pad on any of my boards, but imagine this is what one is like, on the whole board.
I do have the X, but am sure there is no difference.
