Hello,

Recently I remembered about a PDF, produced my Petzl I think, about why carabiners are a bit safer facing the same direction than opposing. 

Does anyone else remember this and able to find it? I can't find it any more and am starting to wonder if I've made it up.

To be clear I'm looking for the PDF, not to start a discussion about what direction the carabiners should be facing.

Don't know about Petzl, but this is good:

Thanks very much for the link, could have sworn it was a PDF Petzl link but I might just be misremembering.
