I use nine of the ultralight titanium tent states from
Vargo. No real downsides I can think of. As mentioned above, I've been using this setup for a very long time. Tried a couple of other approaches (tents and bivy) - this one works best for me. (It is a simple, rectangular 8x10 tarp. It can be pitched a number of different ways, unlike some of the other styles of tarps, where their cuts - asymmetrical, diamond, cat-cut, or 4 season - which kind of 'force' you to only being able to pitch it one specific way. And, some of those other types of tarps require multiple trekking poles, which doesn't appeal to me. To each their own!)
