I'm planning a thru hike for next year. I recently went to Mountain Crossings to have my gear looked over. The guy said I should invest in a bigger tarp for my hennessey ultralite backpacker asymetric hammock. He suggested an 8x10 sil nylon tarp. After researching I've discovered that this will cost probably another $100. Anybody thru hike with this hammock with the tarp it comes with? It hasn't caused me any troubles so far, but I haven't slept in it with really bad rain. I hand my bag underneath and I could see it getting wet in a really bad storm.
Should I get the new tarp? Is there any place I can find one cheaper than $100?
