Sorry to change the subject but do energy gels pass as emergency food? I don't want to carry food if I don't have to cos I won't eat it.
I would think about what happens if you really need the emergency food - if you're stuck somewhere waiting in the rain for a few hours for help, do you want to be eating a horrible gel? Blurgh. Stick a mars bar or something at the bottom on the bag, you'll never notice it.
