Great blog, the ultralight one (above). I bought the same toblerone-shaped tent as mentioned in it, for a bit of fun. My goodness, what a small, light tent when packed. £18 or so, iirc. Of course that blogger is fit as a whippet (he took that tent across more than one continent) and would shake off the odd damp night no problem. I went off and bought a £400 tent instead. The ultralight toblerone tent will get me the third off some future Terra Nova if they're still doing the trade-in deal.
But Bigjim is right, that blog is all about the enjoyment of toying with the challenges of the low weight approach, and often poo-poos the expensive consumerist options by exploring things like home-made plastic gloves (for descents, 2 grams per hand). It's a million miles from a Platinum Amex experience, or even from the bulk of the latest-purchase ultralight shopping/climbing blogs.
The OP tent has good headroom, looks like. I'd be wary in midge areas though.
