In reply to Tyco:
unless any amazing new guides have come out recently, either the "purple" guide or the jingo wobbly one are fine and i couldn't choose a favourite, if you're going for a couple of weeks you could consider getting both as although there's a fair bit of overlap, they do each have some good stuff not in the other. also probably worth getting the French equivalent of an o.s. map, you can get them in bookshops over here. as for mats, you'll get by with one, but beyond that it depends what you'll spend most of your time doing. if you're going to spend all day climbing round easy circuits, then one mat is more than enough. if you'll be trying to push your grade picking off individual problems all day then do what you can to have a second mat. enjoy
