    i've had some slippage issues too, but i hadn't said anything about it because one of the main reasons is the type of webbing i've been using at home.
    but just like you, i found that by adding a simple slip knot, she's going no where.
    one pull & it's undone for adjustment.
    even w/ adding the slip knot, the rings are still the easiest, quickest adjustment system i've used.

    Also make sure the webbing is exactly lined up with itself after it goes through the rings. If the top layer of webbing is off-center to the bottom layer, the friction decreases and it can slip. That's the only time I've had any slipping. I've used Ed's webbing and tubular climbing webbing.

    After reading a couple of posts I think I will also just run a "Bight" back thru the rings to keep it straight and hopefully prevent it from slipping.
    I wonder how much this thing weighs?

    You can pick up your Camp Nano Wire Carabiners here and also your Seattle Manufacturing Rings.
    Save money on shipping versus buying seperately thru Amazon.com

    My local REI had the Camp Nano Carabiners for $6.95 a piece.

    Might work. One thing to be careful about is knots...they reduce the working load by quite a bit depending on what kind of knot you're using. With webbing, 700lbs is enough b/c folks generally don't put knots in it. With cord that you're gonna knot, I'd test it for a while in safe conditions first. The more you use it, the tighter it'll cinch the knot...until one day you're on your butt! I've broken 550 cord twice now, and 725 isn't all that much more, especially once you half that strength for knots.

    Not criticizing or saying it won't work...just saying be careful with it. Hanging the hammock with more sag (i.e. no structural ridgeline) will reduce the tension on the lines.

    I am just trying to find something cheaper than $30. I also don't need 50'. I just need enough for two hammocks.

    During my testing I placed a paper clip on each end of the webbing. Right at the buckles. I can tell for sure if it has slipped or not.

    Go to a climbing or kite surfing store...they usually sell it by the foot. You might have to dig around to get a firm strength rating, but it'll be cheaper b/c you get only what you need.

    one pull & it's undone for adjustment.
    even w/ adding the slip knot, the rings are still the easiest, quickest adjustment system i've used.
    I've found that, for me, whether the webbing slips depends a whole lot on the stiffness the cord/rope tied to the rings, the knot used to tie to the rings, the stiffness of the webbing and even the direction I thread the webbing through the rings.

    If the rope is pretty stiff, a simple larks head or a full turn and 2 half hitches will tend to make the webbing slip if you thread the buckle in the wrong direction. If you look at the rope and rings from the side, you can see that the stiff cord pulls more on one ring than the other with the larks head. The full turn with 2 half hitches does the same. If the cord is very flexible and the webbing is fairly flexible, the webbing will pull the rings even and help alleviate this problem. If the webbing is fairly stiff, then the webbing cannot pull the rings even. If the webbing is then threaded in the opposite direction from the cord pull, the webbing holds. If the webbing is threaded to enhance the uneven pull from the cord, then the webbing will slip.

    3 solutions that I have found to work for me:

    1. make sure that the cord and webbing are both fairly flexible and the problem doesn't seem to appear. The webbing can pull the rings even and the cord is flexible enough that it will conform to the pull by the webbing.

    2. if the cord is fairly stiff, then do not use any knot like a larks head or full turn and 2 half hitches. Any knot in which the force is transmitted mostly by one thread of the knot can make the webbing slip in this case. You need a knot that will pull both rings equally. I have found that wrapping the cord around the rings at least twice and preferably at least 3 times and tying back with a bowline will work. This arrangement pulls both rings equally no matter if the cord is stiff or flexible.

    3. If the webbing is fairly to very stiff, then you will definitely need to go with the wrap and bowline solution since the webbing pulls unequally on the rings and even a little unequal pull by the cord can cause slippage if the unequal forces from the webbing and cord line up.

    Hope this helps in understanding why the webbing may slip sometimes and not other times.

    good observation tee dee. i had noticed that the larks head (in stiff rope) pulled the rings uneven & have planed to try the attachment method that blackbishop used on the cc buckle.
    http://www.hammockforums.net/gallery/files/7/bknot6.jpg
    i will try both that and the multiple wrap w/ bow line like you said.
    i believe you're right... using the right combination of rope/cord & attachment method to the rings, along w/ the right webbing should solve the problem.

    about the rings... i bought two OP alum rappel rings (by omega pacific), 1.2oz... 20KN, because that's all they had at the local outfitter.
    but that's a real overkill!!! (& over weight too)
    i believe the ones shown on a link a few posts back (descending ring by seattle manufacturing, 0.4oz, 16.6 KN) would still be more than strong enough & less than half the weight.
    what's the lightest rings that others would feel safe with?
