The Blend is a fatter ski but the 2012 is rockered a bit so the 2012 is more of a pow ski but id say if your going for a little bit more park then go with the blend for sure
If you hit alot of rails in the park, for sure go with the blend. All salmon skis get ripped to pieces on rails. Otherwise if you mainly hit jumps when your in the park, get the 2012's. If your hitting rails, without a doubt get the blend!
