Nice post. Only two issues with my thoughts from late Sunday/early Monday is that I rushed the RI by about 12 hours by underplaying the initial shear a bit, and probably need to adjust west a tad.
There is quite a dichotomy among the top analogs and it's due to the behavior of the polar domain...this is why I attempted to use the solar cycle and QBO to gain insight into that a couple of week back.
Yea, extratropical refers to much more than polar.
I see what you meant earlier, maybe I posed an incorrect link. This one works.

It makes sense to me because they don't have time for ERCs and other fluctuations. Most storms don't sustain that intensity for long, so you want rapid spin ups.
What is your issue with that title? I have no clue what you are getting at...preliminary analysis of the polar domain for winter..IOW, my first thoughts about what the polar area may or may not look like this winter.
