All the reasons for the different set-ups makes me glad I got my Kondos version of the Dri-Fly.

With 3 sides protected, the odds of the wind changing 180 degrees to the front are pretty small. I can pitch it close to ground in inclement weather, or higher off the ground when I want a 360 view.

On cool/rainy nights/days, the 3 sides hold the heat in from a nice campfire. At the same weight as a similar sized tarp, it's worth a look see IMHO. Built tough and has multiple loop attachment points.
