Ouachita Hiker here. I am new to the forums but this is a subject that I am well familiar with. About three years ago i bought two HH EX. Asyms. One for my wife and I. I strung one up and set down on, like a seat, and the ridge line broke. Bought it from REI and they replaced it. The second ones ridge line broke back in Nov. on a Bping trip. This time my wife was in it and the ridge line slaped her face and left a welp. I think the cause, at least in my case, was that they were strung up to taunt. I sent the second one back to REI and they gave me credit.
