In reply to robw007:
I have a Hilleberg Akto which I love. Very stable and room enough for me and all my climbing gear, can cook in side it fairly easily, and space enough for wet stuff. It's very long too so perfect if you're tall. The first time I used it was solo camping at Cwm Cau at Cadair in 50+mph winds, gusts which blew me over so I'm thinking gusting 70 odd, and driving rain all night. Because I hadn't used it before I basically spent 11 hours cowering in the tent waiting for it to break and all hell to break loose. I had had enough by about 5am and struck camp in silly winds and sideways rain in the dark, and it was very easy to strike, which says alot about its practicality in heinous conditions. It stood the test gallantly though, and I now have every faith in it's stability in strong winds, and always sleep very soundly in it. You can also strip out the vestibule and just sleep in the fly with a footprint if you want to go really light.
There's a few videos somewhere by a guy from Northumberland putting one up in the Cheviots in some pretty hairy winds, and taking it up in winter and waking up with snowfall over the tent, and it was fine. Here we go, found them:
Downsides are that they don't come cheap, and there are lighter options out there, but for a light solo tent they're pretty damn nails.
