I actually own a pair and have rode them for a season, here's what I can tell you:
Not too stiff, not too soft. They have some good flex in them which is pretty enjoyable. I ride open powder, glades, bumps & groomers with this ski and it's pretty sick in all those areas.
Bases are great, on the way down from a bump run or the backcountry I usually cut into the kiddie park and hit a rail in there, so that was like 20 rail hits and on ski was totally unscratched on the bottom, the other (front right foot) was pretty scratched but no real damage. The rail is rough too. However
, the topsheets on these aren't the greatest, I have numerous small cuts and scrapes, but nothing very deep so they're not affecting the ski so I have no problem with them.
Unless you center mount these, I could ride park with em. I don't normally ride a fat ski in the park, but I took these in there a couple times and the mountain position (for pow) was too far back for park and felt awkward. If you have a pair of park skis, save them for park riding and use the ARVs in the powder.
