I grew up in New England. There are a few places in New England that can get powder (Jay Peak, Stowe, Sunday River), but they tend to be remote and powder is not regular like it is out west.
For going on backcountry/sidecountry trips with your dad, I would lean towards a directional board that is powder friendly... instead of a powder specific board. There are dozens of boards that match this profile.
While I haven't ridden the Never Summer Cobra... I have ridden the Never Summer Evo, Proto CT, SL and Summit models... and since the Cobra is a hybrid of the Proto, SL with a tiny dash of Summit, I can imagine what it would be like. That is why I am recommending it.
Again... many other boards out there. I'm just suggesting the ones I have personal experience with.
We aren't going to be staying in NE. And, I can't do directional, I switch constantly
