I just picked up a Hennessy Backpacker asym in sil-nylon on sale for about $50. I already have a Superfly, I bought this for day peak-bagging trip insurance, and a fair-weather fly for my wife. My wife has a 10ft hammock. Does anyone have experience hammocking with this tarp in in-climate weather? I'm concerned about the fly's effective coverage in a rain storm or summer squall. Thanks all.
