If anythign the changes to the Hatchet make it an even better board - the Rocker used on it, is a hybrid rocker, where the tips are rockerd with camber underfoot - on Atomics version as you pressure teh board the rocker kicks in. It does not ride like a board with rocker between the bindings, e.g Skate Banana, but far more like a traditional board, but more playful, better in pow, and of course more forgiving.
The hatchet is a great board, one of the few boards that is as much fun for a learner as a pro to ride, and untouchable value for money at the price.
Good review here
