In reply to Chris Ellyatt:
cordelette is a useful tool to have in the box. Good in some circumstances, for many other circumstances it is a bit of a faff and just one extra bit of kit to have to carry.
they are good if you are doing something like abbing into a hanging stance or planning to lead in blocks. As has also been pointed out they don't equalise meaning in most cases there is a single bit of gear taking most of the force, which most of the time isn't a significant problem but may be an issue if the gear in the belay isn't totally bomber.
90% of the time these days I just clip a half rope to each anchor point and clove hitch back to my harness as Simon suggests as I've found it to be the most efficient solution in most cases.
> After reading about them, I'm surprised anyone even uses the traditional method. Are there any drawbacks to using a cordelette?
As with most things there's no single 'best way' to set up a belay. Each situation is different in terms of the anchors you have available and what you are going to want to do with the belay. Some situations will lend themselves more to a cordelette, in other situations is faster, and potentially a better anchor if you tie in directly with the rope.
It's good get in the habit of thinking through why you are doing things a particular way and whether you could be doing them differently/better. Have a play with a cordelette, but try not to fixate on one single way of doing things. Practice evaluating the systems you are using, work out the pro's and con's of each method and the best solution for each individual situation.
