Contingency anchor issues

    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?

    Pictures and a much more detailed description of what happened would be welcome.

    To answer your questions briefly:

    1) It *might* be suggested to rig all raps with a contingency, depending on the water hazard, team member skill levels, etc. In general, many folks rig most everything for contingency in Class C, but few do in Class A/B.

    2. A picture recently appeared in a post on FB "Canyon Rigging" group showing a stuck Fig. 8 block. Perhaps yours is the same one?

    I rig them all contingency anchors when I'm taking out Boy Scout groups, but that's because that's a requirement. When I'm out with friends, I generally don't. But I don't really do much class C either.

    When I do rig a contingency anchor, I use a munter/mule. First, because I think it's easier to use. Second, it's an extremely handy self-rescue knot. Third, there's no additional gear (like a figure 8 and a rapide) to carry with you. Fourth, you can't drop a munter/mule, it's a skill not a piece of gear. Not saying you can't get someone stuck somehow with a munter, but it seems a little harder than doing it with a contingency 8.
