I am preparing for a Himalayan Expedition which requires a trekking pole at the altitude of 16000 ft and melting snow condition. I haven't used any aluminium/carbon fibre poles yet.
I usually find a wooden hiking stick in the woods and only use them when fording streams and hiking up and down steep slopes. I toss them back into the woods when I am done with them.
I am about to buy a Trekking pole but this question is bothering me: whether to buy a pair or a single-pole? Obviously, it seems the pair would provide more stability but it will also double the weight(avg 230g per pole).
