Well why not demo them yourself? All people here can do is tell you there opions, and there only that opions. You are the only person who will know if you like the flex, swing weight, sidecut ect ect.
The blend is genrally pretty soft and buttery, so will be fun to mess about on in and out of teh park, but it wont carve and charge to well.
In comparsion the 2012 is stiffer underfoot which makes it better carving, however even with it being stiffer the rockered tip and tail make the ski quite buttery. I had a set last year and there fun in teh park and charge round the mountain.
So if you want a soft ski get the blend if you like a little stiffer but still playfull get the 2012. Not sure what you prefer demo them.
