I'm trying to decide between the HG and the Zpacks hex tarps for hammocks. The z packs offers a bit more coverage, but my main question is the stitching. HG boasts no sewn ridgeline while zpacks boasts about their sewn and taped ridgeline. Which is actually better? I can imagine you might get a little more strength with the sewn, but might save some grams without the stitching..
