I'm new to "hammocking" and backpacking in general, trying to put together a good set of lightweight gear. I'd like to know if there are any tarps on the market that would work well for both hammock and ground systems. I have my eye set on the 12' HG standard cuben fiber tarp with doors (only 6.5 oz!). I'm thinking this tarp could be used on the ground with two trekking poles in place of the trees, has anyone tried this? I apologize if this has been discussed at length, if so I would be happy to be referred to the relevant threads. Thanks!
