Depends on how much wind you are prepared to camp in! I used my Zephyros 2 on the summit of Moel Siabod when it was windy enough to blow my daughter over. The tent was fine, but we didn't get any sleep because of the noise. I have now got a Superlight Voyager. The only time this has failed me was on the summit of Moelwyn Mawr. I ignored the MWIS thunderstorms and high winds warnings. About 3am, following a thunderstorm directly overhead, it was so windy that the poles were being pushed in, although all the pegs and guys were fine. I packed away in torrential rain and ran for the valley. The tent was undamaged when I pitched it at home.
