Review Spidersling with Arboring I can’t review on the difference between these and the X-rings, sorry. First things first, high build quality is obvious straight out of the box.i love the fact you can adjust the sling like a whoopie, the plate works a treat. Also the way it has been designed means you can use it to clip a pulley block into the loop (pictured) this makes it versatile and a great redirect. When you think about the price of a whoopie sling and a pulley in comparison, there not bad value either, a kind of all in one lowering sling. If your in the market for some lowering gear a few of these would really be worth a look at, the plate is also sold separately to convert what you already have, along with various length and diameter spiderslings. Also they can be retrieved from the ground with a little clip and ball (similar to a cambium saver) Any negatives? Friction, but nothing to noticeable, in fact there is no harm in a little bit of friction at your anchor point in rigging, but if you like everything low friction, you will notice. So in conclusion, quick, simple, adjustable, versatile.
