If Danner's fit you well then I'm sure you'll like the 1200 for late season with a good sock system. FYI I have the Pronghorns uninsulated for pheasant hunting and the High Ground 1000 gram for mid-late season in Minnesota and have been happy with them. They are good up until it gets down to 10 degrees or less, then it's time for the Pac Boots.

 

I think at that temp size and amount of sock you can get in there matters a lot. I’d go to a place you can try them on and bring some gooood proven heavy wool socks

 

I liked the ankle support the Pronghorn 1200 offered. In the Pike Co. PA, the cold cut right through them.
The Baffin Apex boots are what I ended up with. You buy a size larger for those boots and your feet stay warm. The boots aren't the most supportive but the insulation can't be beat for a pac boot.

I've been wearing the 1200 gram the last several late seasons. I wear a liner sock and heavyweight darn tough in them. My feet have been fine. I do have a "welcome mat" that I cut to fit platform of my stand. That eliminates boots to metal.

 

I wear the High Grounds, not a Pronghorn fan. For ME, Arctic Shield boot covers over 400 gram boots are better option than heavier insulated boots. Plus you can add chemical handwarmer packs.

I can’t walk far in 800gm+ boots without sweating, which ruins long sits for me.
