I'm working on a project where I need to know the ridge line length of the HH Expedition and Survivor. I check HH's website and have sent them email. I'm sure I'll hear back. But right now I'm stalled out. If someone has one or both of the ridge line lengths, please let me know.
I suppose I could assume - what is that percentage, 83? - a percentage of the total hammock length, but as both the Expedition and Survivor already have a fixed RL, there is no reason to guess.
