I have been using a pair of Karrimor xlite carbon poles now for 2 years +. I generally use them only use them in the hills... Lakes and Pyrenees, BUT have used them on flatter ground when it is very muddy for balance.
The Karrimor poles are light, fold down small and are robust.. I have used mine many times for vaulting swollen streams.
A good piece of gear at a really affordable price.
the GR10 will have a lot of snow in the areas around Cauterets in May and early June.
I was in that area for the second half of June and needed trail spikes to get across snow and icefields and in some parts it was still entirely covered and could not see where the lakes were hidden under the snow
I generally tale little notice of the "professional" reviews and tend to rely more on reviews from users and mainly make a choice based on those. If an item has an overwhemingly good set of reviews I will probably go for it and conversely will not buy if majority opinion is poor.
