Just to be clear, seven crossing points, created by four equal-length poles. Very strong (and, as you note, relatively heavy at 10 pounds).
Fantastic pictures! Good to see both tents stood up to the snow loading so well. I tried the Saivo but found it too cramped, vestibule included, and so went with the Jannu for my smaller winter tent. Haven't regretted the extra weight yet for solo use, though I tend to use a pulk most times in the winter these days, not a pack, so that makes the weight easier to bear.
Two with winter gear can squeeze into the Jannu as well, which seems out of the question for the Saivo and Scarp (though I'll be curious to hear what you think).
