i'd go w/ the machete too. it's not a camber nor a rocker. literally flat between the contact points with a slight rocker at the tip and tail for powder. it's a great aggressive all mountain.
this is what i ride.
i ride a lot of groomers, and it's handled great on ice at a fast speed, a little skidding, but nothing where you lose control. can't give you any input on how it handles on powder, but it's supposed to be at worst... descent.
I ride a 155 cm, at 160 lbs
