Mesh tent & tarp set up - how's yours?

In the warmer seasons and in warmer climates I'm starting to get into packing a mesh tent and stringing a tarp over the top, rather than packing the tent. Saves quite a bit on weight, more versatility, and seems to generally be the go to for summer hiking.

How's your set up for such situations? In the woods pitching is fairly straightforward with easy ridgelines etc. but how are you working it in the alpine above the treeline? Trekking poles for the tarp and cordage run between the two to attach the mesh?
