Luckily for your opinion, we have SCIENCE. It's all about surface area, but I will hit you with the plainest way I can think of expressing it.
Imagine your ski is a butter knife, and the snow is butter. You press the knife flat against the butter, can it cut? No. Now angle your knife the slightest bit (mimicking your ski on edge) can you cut? Yes. That's because your knife doesn't float.
Now go get a spoon, and try the same thing. You would need the human equivalent of a metric fuckton of weight to prevent that spoon from floating about the pow, or a retardedly high edge angle.
Now, I do think Atomic took the wrong route when trying to expand their tip's surface area. Do not use the sidewalls and turn them into the base. That sounds like a horrid idea from a durability standpoint. Especially if it is soft ABS. But hey, if that's the technology it takes to mass produce a ski of this kind, at a reasonable price point, then so be it.
But DPS has the spoon technology down to an art, as they do everything else...
***Disclaimer: I am not saying DPS doesn't have a reasonable price point, you get what you pay for.***
