In reply to Simonfarfaraway:
It’s just luck of the draw how a turbulent wind hits your tent. I did an Icelandic trip in a Terra nova Voyager (so three season), late September, on one windy night three NSR hubbas suffered broken poles, and the cheaper festival tents on the site also suffered, while the voyager was fine. A cheap Italian ??Ferreo/ferrino?? also survived next the voyager.
It has put me off the wish-bone MSR design, but I can’t say that is a fair conclusion given the adjacent cheap tent surviving.
Personally I’d go with a decent three season tent, rather than lug a four season around. If it’s bad weather retreat to a hut, or if on campsites with large 4x4s (which is common) ask to pitch in their Lee.
