I recently had an incident where a contingency figure 8 bound (stuck) the rope with a rappeller 5 feet off the deck. This wouldn't normally happen but we were practicing lowering and it turned into a serious situation. Yes, in hindsight we should, and will in the future, have lowered the rope all the way down. We did tie a knot in the end of the rope. We were able to finally release the stuck rope before rigging a 4:1 pulley to release the tension on the 8 against the rapide. Two questions: 1) is it suggested that all raps be rigged with a contingency? vs. a clove hitch on a locker I can see the logic, especially setting up a rap down a waterfall in case a rappeller gets stuck and needs a quick lower. However, it would be more of a hassle when setting up a pull cord retrieve? 2) Has anybody else experienced a stuck rope using the standard figure 8 contingency? pulling a bight through then over the end with a twist or not? I was made aware of the "Euro 8 braid" that utilizes a daisy chain of the rope vs the flip over the end, any experience with this?
