Neither anymore. Now it's tarp or hammock. If I'm really trying to cut weight, my tarp system (poncho shelter) is less than half the weight of the hammock (Hennessey Scout). However, for comfort and ease of setup, the hammock wins and I'll leave something else home to make up for the weight difference. I've not used a tent in many years and bivies in Texas are hot in all but the coldest days.
