The Moment's rocker looks like:
Sorry for the phonecam pic, it's mine from last year before i got them mounted. Its a long gradual rocker, they do ski short but they kill it, I thought they were less chattery than the anthem and a great ski. Oh and i'm 5'8 135-140. I would have gone 5cm shorter in an ideal world.
Basically the anthem is soft and buttery but still a pricepoint park ski. The Rocker is a top of the line park ski, better durability, light weight (much lighter than anthems) but actually the flex is more medium-soft. The rocker makes them buttery but for me they didn't flap about too much.
