In reply to Timmd:
It looks similar to other tunnel-like outer-first-pitch tents (I have Force Ten Helium) and even though it's nearly twice as heavy as true lightweight tents, I can't see how it would work in Scottish winter.
It heavily relies on pegging though. I had a bad night couple weeks ago in F10 Helium tent in Arran - 3 out of 8 tent pegs were pulled due to heavy wind (60mph IIRC) and very soft ground where I camped. The tent held, but it was quite loud night due to the gusts. If the tent is pegged correctly so that there is very little slack (and it does not rain at night), the tent can stand quite severe conditions.
I am not sure whether it is worth the price given how heavy it is.
