I recently purchased a Mountain Laurel Designs Grace Duo tarp in spectralite and a Serenity shelter. The pair weigh 16 ounces including all required tie outs. I'll use 4 titanium shepherd hook stakes for the Serenity, 4 to 6 MSR Needle stakes for the tarp sides depending on weather conditions and 2 MSR Groundhog stakes for either end of the tarp.
Here is a short video showing the setup and features of the gear. I intent to follow up with a field report after my first trip with this gear the weekend of July 12th. Stay tuned!
