I enjoy using a small Clark rain fly, more than 30 inches shorter than the Micro. The silnylon is not heavier gauge than OES, but the bare Clark is heavier in total weight, even without grosgrain hems.
Huh? well the cutouts are non-existent, so there is more coverage. There's the rub. IMO: Every hexagonal tarp with deep cuts in the end overstate coverage with the raw size dimensions, as though the weight savings of deep end cuts did not come with some sacrifice.
If your hmmk is DIY, or even if it isn't, I'll suggest sewing, snapping on, or velcroing some rain-shedding hoods for the hammock ends, oversized triangles of fabric. Bingo: Reduced vulnerability to wet even with hexagonal rain flys.
