Absolutely love this board!
I LOVE the K2 Zero! I rode this board ~30 days over the 2009-2010 season and never regretted spending the extra money for an amazing upgrade! I didn't get the opportunity to mix it with the AutoEver bindings but I've been riding it with the K2 Cinch CTX and they're awesome for quick action.The only problem I've noticed is that the softer material on top shows a decent amount of wear fairly early, not that it changes the ride (forget about stomp pads too! it grips your boot perfectly).
Super-light and mildly flexible
Best for powder runs over pipe
