You're referring to skiboards, right? It pays to know the difference.
On my 125cm Marauders (considered a longboard.. <110 is standard skiboard typically with fixed bindings) I found them to be no good in real powder and these have 147mm ends. I had to lean back a lot to make sure the tips stayed above the snow and my legs got tired quick and there was no room for error. If they got too far below the snowline I'd somesault forward and fly out and lose the skis. That said, the powder was heavy. Just compare skiboard dimensions to true powder ski dimensions and determine if someone is stretching the truth if they call skiboards backcountry machines. In a word, too much lean back in powder (it's even in that video). But, I think skiboards are slowly adding rocker, and you can set the bindings back and these would both help. Skiboards have limited application but within that scope they are tremendous. I found it difficult to really charge the mountain with them, they are simply just too short. I wonder why we don't see more in the superpipe. That'd be a site to behold.
People that hate them are very fearful, cos great skiboarders could destroy them off the side of the mountain. Probably some gun rollerblader on his 3rd day seeing snow. But stay tuned to the HCs which have been built, they should be able to blitz almost anything.
