For the "for what it's worth" file:
I started skiing in terrain like yours -Kapuskasing Ontario, flat and in the boreal forest, with skis similar to the Amundsen (the original stiffly double cambered Europa 99's 210cm with aluminum edges). Lakes, snowmobile tracks across the muskeg, camp service roads (secondary logging roads), lakes, etc. Very similar snow conditions by the sound of it. Learned to use polar and special green wax for much of the season. I used them in local loppets (20K events) , the Canadian ski marathon (longest day 30+ k if I remember correctly), winter camping, ice fishing and cruising in the set tracks -all around skis. The only downhill in that area was the local ski dip (150ft vertical

) that I would try to do long telemark turns at slow speed in deeper snow before the "downhill" season started. Downhill on the CSM tended to be snow plowing on polished hard pack. The skis worked well for all of these pursuits
When I moved to a hilly location in the shield country the cross country downhill bug hit: to "practice" my turns, I evolved through a compressed telemark history (narrow skis/light boots, wider skis/double leathers to wide shaped skis/plastic boots) to play at the local ski hills with our alpine skiing/snowboarding children. It was also a great opportunity for family trips to the west and eastern "big" hills. The trouble was, most of the local boreal bush was too tight to allow extensive telemarking and, located on the windward side of Lake Superior, we didn't get many powder opportunities, so local "earn your turns" backcountry skiing was mostly "earn" and not too much "turn".
Last year, after being away from skiing for a few years, I decided to "go modern" backcountry XC (no D) (with the nature of our terrain in mind) and picked-up some Amundsen skis, 201cm for a 183cm, 88kg, the "Fram" version and NNNBC bindings/boots. They immediately reminded me of the old 99's, but with more stability (width) . Definitely "cross country" skis, fast cruisers in the harder base and set tracks, tracked straight on hardpacked snow, nice in 20 -30 cm of new snow over a consolidated base -to me a classic ski for the nordic conditions you've described. Even though these (Fram) are slightly stiffer than regular "Amundsens" they worked well for me (with a day pack; extra clothes, tea, wax, tools, etc). IMHO they are great XC touring skis for the conditions around here, not Nelson BC or the Chic Chocs, etc that we all dream about.
I guess the point of this "wander down memory lane" is that since you've narrowed your search to skis that realistically suit the terrain/conditions in which you'll be doing most of your skiing you will likely enjoy whichever ski you ultimately select.
