That would never be my choice. I am most certainly NOT good enough to ski an Ikonik 84 out west every day. I have skied a 105mm wide ski as my one ski quiver out west every year so far.
And my wife, who has some nice 65mm Elan skis, hardly ever touches them, even here in MN, preferring her Fulluvit 95ti.
All this is depended on the skier of course: your skill level, your preferred feel, your preferred terrain and preferred skiing style.
In our case, we are intermediates, rarely ski groomers out west, 80% of the time we are trying to find interesting natural terrain or lapping mogul runs. We also don't ski very fast, instead more about picking our way down, finding pockets of soft snow, slaloming around trees and boulders, pumping rollers, etc. I also really like, a loose and surfy feeling.
If you typically drive out west, I would absolutely take both the K2’s for groomers laps, AND a pair of >100mm all mountain skis for the majority of the time.
Because, based on the skis you picked initially, you are not looking to travel out west just to rip high speed groomers.
