Planning a trip to Norway, and the only potential problem I see is running out of trees. My Hennesy Ultralight Backpacker is highly capable... But it ain't magic. Any tips on how to suspend the ridge line and tarp with only two poles? What lightweight poles would you recommend? Also, I won't be bringing a pad. With a JRB nest and no sniveller and tarp beneath me, would I still need to worry about insulation from the ground, it would these be sufficient for staying warm?
