I'm looking into buy either a new 2 person, 3 season tent by Black Diamond or twon Hennessy Hammocks. THe Hammocks are much less expensive and it seems that they are adequate for all types of weather and situations, but they aren't tents. Does anyone have any suggestions, or even better, does anyone have any experience with Hennessey Hammocks or similar all season, all weather hammocks? How are they in cold weather, how is gear storage? Thanks.
