I mean it's a different ski. Punx is a much more well made, better ski. But it's more expensive. The biggest pro of the mastermind is that its inexpensive, and honestly if it's serving as a park ski and you're giong to beat the shit out of it anyway, why go broke on it. I think the price point ski is a good idea, but if you want higher quality, definitely punx.
And here is where I realize why I injured myself knuckling 3 times in 2 seasons.
But don't let this keep you from buying the skis. Waxing is an easy fix, one I wish i used.
