If one looks closely at the Akto solo tent and then at Tarptent's Moment, Notch and Scarps your can easily see the "theme and variation", with the Akto setting the theme of single hooped tents with vestibule(s).
Henry Shires took the Akto design and added his own genius of design.
But for me the Hilleberg Tarra and similar Hilleberg designs would be my choice for a Greenland-type expedition. They are bombproof and one could easily sit in the tent snd cook in a dug down vestibule in bad weather.
"Snow load" is often discussed but most tents, even many 3 season tents, can withstand VERTICAL snowload. But when the snow slides down and builds up around teh tent sides it presses in a lot, reducing interior space. This is what I call "side snow load". Often one must get out at "0 dark thirty" to shovel snbow away from the sides.
True dome tents (NOT wedge tents) with plenty of poles running down the sides are the ones that fare best with side build up of snow. (I know Roger Caffin loves tunnel tents but they too are prone to distortion from side snow load.)
