Complex Figure Eights

The Emery eights are interesting articulated eight. I don't see why the articulation is needed. The Frendo eights were made for canyoning, and I can see that they would be quite useful in that situation, where dropping one's rappel device is both easy and inconvenient. The Young Manufacturing Rescue Safe Eights are well-made devices that provide an innovative alternative to the Figure Eights With Ears, addressing something that I don't view as a problem in my world, but apparently concerns many people in theirs.

The weight chart shows that the complex eights are heavier than the average standard eight, but much lighter than many.
