I bought a WBBB and am using a Kelty 9 tarp which is much too big and heavy. I was wondering if anyone could tell me which tarp would work better for 3 season camping, the Asym-Diamond, the Edge, or the Mamajamba? I'm looking for something for backpacking that i won't get wet under. If anyone has any pictures of any of these tarps over their hammock or another light weight tarp it would be super helpful.
