I'm planning on buying the Burton Ion boots to upgrade from my invaders. I ride groomers and powder when it snows heavily. I also take the occasional jump. According to what I've read I would want a stiff setup. Are the Cartels stiff enough for my needs? Are they responsive? I'm sure they're be a hell of a lot better than my freestyles but is there a binding that suits my needs better than the Cartel? Also what is the difference between the Cartel and the restricted model?
