WindSaber – SlingFin

Hilleberg - Hilleberg Soulo BL 4-Season Mountaineering Solo Tent

Anyone with experience on these two tents? Looking for a harsh weather backpacking/mountaineering tent. For use in Patagonia, Iceland, and Norway. And for summits like Mt. Rainer/Baker.

They both look to fill a similar role, but the poles are different (thicker on Slingfin) and the fabric is different (thicker on Hilleberg BL).

What seems more important? Thicker poles, or thicker fabric?
