Jeff and Jon, thanks for the advice.
Given that it is such a new jacket, I wasn't sure where it fit into the pantheon on down parkas already on the market and I didn't feel MH's website was too clear on that. I talked to MH customer service and the guy I talked to recommended the Absolute Zero for Denali still because the Nilas is more designed for Ueli's system (for people looking to move super quick and fast) than for an expedition-style climb like Denali.
It might be warm enough and guides might recommend it in the future, but I don't need to an early adapter when it comes to this, so I am going to go with the Absolute Zero just to be safe.
