I found the Hilleberg Nallo 3GT had excellent build quality and was very quick to put up / take down.
I did find however, that the claimed weight was inaccurate, and the lightest I found after weighing 3 in a shop was 3.1kg. It was also very noisy in medium strength winds,however well pitched, which seems to be a common problem.
I have now sold it and have 2 Terra Nova tents - a standard Laser for single traveling, and a Solar 2.2 for more comfort or together with partner and couldn't be happier.
One tent which doesn't get mentioned very often is the new Vango Force Ten Nitro 200+, it has an accurate weight of 2.25kg, and a vestibule similar in size tl the Nallo 2GT, allowing to get the bike in the porch after removing the front wheel...if only it wasn't orange inside I would have gone for one.
