NMMediaI had a pair for 2+ seasons. Not my favorite ski ever.
My main gripes with it:
-Was ok on rails, nothing special, if anything I like a little camber better since they never seemed to lock onto rails well. The flat profile didn't make it any easier for swaps/etc in reality
-Horrible at gripping ice
-Horrible at high speeds (shitloads of chatter, felt like I was going to die all the time)
-No pop for jumps
-Really heavy, both weight and pretty heavy swing weight in my opinion
-Pretty bombproof, lasted me for about 2 and a half seasons of park shredding, their downfall was a fucked up lincoln off a knuckle to a backseat landing, snapped behind the binding.
-Usually the graphics are pretty dope (I had the old pair with neon pink and orange bases, shit had sweet underglow for impressing gapers in the lift lines)
Yeah they are very cheap and durable skis. So OP it comes down to what you want out of the ski. It is very soft, so like said ^ it will be chattery....but you will be able to throw butters like a madman. And the lack of camber will obviously give bad grip on ice. But unlike ^ I did notice a slight difference in the surface swaps...they felt a little easier. Also i didnt really feel like they were harder to grip rails, but to each his own. And the pop will take a little to get used too since there is no camber to help you out, but I didn't see it as a bad thing after a few days.
They are a little heavy just like all k2 skis, but that's the price for durability! Mine have been through 2.5 seasons. (Although more like 1.5 due to me not skiing to much park this year).
I got mine for $250 brand new, and I couldn't be happier for a nice buttery rail ski.
