In reply to Flinticus:
I've always pitched it end into the wind and not had any problems, but even with wind shear, I've not noticed any issues once its pegged out well. Of course it will flex and get buffeted about, but it seems pretty solid. Because it is a small tent, those side panels are actually that big, and its shape is pretty aero both across and end on.
Did you watch the video? That was a windy day, you can get an impression from the heather moving and sun coming in an out despite it obviously being sped up. You do see the tent flex, but it's not much. It's really well cut so pitches drum-tight.
I should add though I'm a bit of a tent-pitching perfectionist. I find it very hard not to judge people for sloppily pitched tents and have to remind myself that a loose guylines and saggy fly sheets doesn't necessarily reveal a poor moral character, although I have my suspicions.
