Not sure you need them even there. I just got back from the Heli ski trip in Greenland, with deep pow every day and the last thing you "NEEDED" was a rockered ski. I would even say that if you wanted to ski at speed in larger GS turns in some of the bowls or down some of the steeper faces, the last thing you would have wanted was the DPS 112. I skied the Icekantic Shamans the whole time and they were perfect.
sometime people justify their gear purchase so much to keep themselves believing that it was the "right" choice.
when I first saw this video I thought you were out of (for and aft) balance, stemming and lacked flow and dynamics, I doubted you even needed shamans to ski that but then again I actually do think you could have been more dynamic on something else
this is very similar terrain/snow only difference is a hiked an hour to get to this point and less people were there before me. I think you can get more dynamicss and speed using a bigger board with rocker even in wide open easy to ski western powder.
I am at 2:34, i am also followed later in the video.
the thing is judging by your picture I think your probably a better skier than me but the closemindness on gear and technique lets me excel at places your rigid teaching system and gear beliefs will not let you.
