I have a Karhu Pyxis with 3-pin bindings + cable which while I personally have yet to use them in Baxter, were described to me by a season Baxter veteran as the perfect Baxter ski. Control, width, edges, and heel lifters for the climb from Roaring Brook up to Chimney Pond (which needs a sturdier ski than the Tote Road).
I personally dislike skinny edgeless xc skis once I'm off xc-specific groomed terrain and onto completely ungroomed or partially packed. Many of the places I've skied in the Whites consist somewhat of snowmobile routes, so that's what I mean by packed.
I also have a pair of Fischer Outbound Crowns, which area nice because despite being metal-edged, they're skinny enough to use on groomed xc trail in the tracks without damaging the tracks. However, what happened to me was that I put 3-pin bindings on them, and they tore out. When I talked to someone at a more competent ski shop he told me that while being an excellent ski, it's simply not built to handle the torque of a 3-pin binding. I will eventually put NNN-BC or SNS-BC on them and use them for touring. I think they'd be perfect for pulking into Zealand. I would want the Karhus if I were trying to pull a pulk into someplace steeper.
One other important difference between these two makes of skis: while both are waxless, using a fish scale pattern for traction, just like a bellybutton the Karhu skis are "outies" while the Fischers are "innies." In other words, the fish scale pattern protrudes beyond the surface of the rest of the Karhu ski, while the pattern is carved into the surface of the Fischer ski. The net result is the Karhu has more traction and the Fischer correspondingly glides better.
