Out of those options there, Hellbent or EP would do you okay for what you say you'll need.
I really find PNW snow to need a little bit of a stiffer ski than those, but I've never had a season where I get the luxury of choosing the days I ride so that I always hit the fresh and deep days. Something a bit stiffer gets you around in more variable snow, and it does make doin drops and technical stuff a bit easier than something soft that may wash out when you land a bit back.
Obviously, you should check out our 181 Caylor, which was designed in the PNW for the PNW. If its not an option though, I'd go with either of the two that I previously mentioned. Its kinda a tough choice though, all of the skis you mentioned are pretty good pow skis, I wouldnt consider any of them 'bad', just some are more apt to different riding styles.
Little of what I do has any meaning or lasting significance.
