Well, just to add a small contrary opinion. I don't like the DD 3x3, I think it's too big, and too heavy. Where I've been camping I often haven't found the space between the trees necessary to for a 3m long tarp...
I have a British Army Basha, I don't use it much, it weighs over 1kg. Far too heavy.
I have a Miltec Flecktarn tarp. I use this a lot, plenty big enough for 1, easy to put up, ~450g (don't have the numbers to hand), so pretty light.
The other tarp I've been using a lot lately is the RAB SilTarp 1. At 198g it's stupid light, It's a bit small so perhaps not one for really tall users, but I've not found it too small yet.
When I got the SilTarp I considered the Alpkit Rig 3.5, it's not much heavier, but ultimately I got the Siltarp 1 on special offer. I've considered a Alpkit Rig 7 for canoe trips where weight is less of an issue, but it also will have issues with finding enough space between the trees...
