obSETHed. They are good enough for Seth Morrison:)
Seriously though, that is a goddamn fun ski. Hope you can get to try a pair and not just take my word for it. Wide enough that it floats in pow with the added benefit of tip and tail rocker, but you can still rip them in the park just fine.
Seriously both of those skis are awesome. My buddy has Steezes (S6) and I love ridding those things. But I have also spent many days on the obSethed and like those too. In this case I may have to say get whichever one you can get a better deal on.
