I have a Moss Heptawing from way back when. MSR had purchased Moss for their popular wing tarps. The E-wing that you're looking at is a modern progression of it. Mine still works great after all these years. It's versatile as it allows you to pitch it high if you want ventilation or pitch it low to the ground if you want to keep wind out. If you use your bike as the prop, it's more of a challenge to get a tight pitch though.
