    1.75 zing-it whoopie

    With a 400 pound breakage rating, why can't I use zing-it for my whoopies? I just made a set and they with just fine, now. Will they fail in time?

    I think the common consensus from this thread and this thread is that you need at least 1000 lbs because the force is calculated differently (you exert more force hanging on an angle - see ultimate hang calculator)

    That being said, I'm more on the experimental side of things, so I would use them. My expected lifespan is predicted to expire within 2 months.

    Also, they are less durable according to several people (which may mean that they will fail sooner in time than, say, seatbelt webbing).

    1.75 zing-it whoopie

    You are welcome to try anything, as long as you're not hanging above me
    Don't forget that the forces in a hammock ate not entirely static. When getting in and out or rolling over, there is the additional (and significant) load on the suspension.
    Then there's the fact that the ratings are for new material. Some discount should be taken for wear & tear, not quite perfect splices, etc.
    But, hang from sewing thread if you wish. In that case, I would recommend the good stuff, Gutterman.

    Yes, others have reported it's a wonderful suspension cord. I'm going to skip all the very valid "lack of safety margin/dynamic forces" arguments which have been thoroughly covered (and I suspect you've read) and simply ask why? What is to be gained when Dynaglide, which is also dyneema and is actually 1.8 MM (vs Zing It's 1.75 mm) has a 1000 lbs average breaking strength?

    Remember...at best, brand new with a perfect splice and tested under ideal conditions, a whoopie sling will have about 80% of the rated strength. That's 320 lbs.

    HYOH, and don't cry if you get hurt :-)

    But I'm with gmcttr: What's the benefit over dynaglide? 0.2oz? It's not cost, it's not bulk, and you're giving up significant durability.
