Okay so I need a new tarp. Up until now I have been using a cheep PU coated nylon diamond tarp. I want my next tarp to last me over the next couple years until my thru hike of the AT and through that hike. I am so torn as to what to do. I think I want a winter tarp with doors so that when I do my thru I will have complete coverage. Then it leaves the choice of sil vs cubin. Sil in a winter tarp would be heavy but I hear it is more durable and lasting than cubin. Also I could buy TWO sil winter tarps for less than the price if one cubin. I don't know someone push me in one direction or the other please!
