In reply to jamesfrome:
Any type simple, light and packs (folds/telescopes) up short, so you can fit it in duffle bags and packs. Too many poles now have fancy grips and shock systems, but they're useless and added weight and expense. Poles break, you lose them in rivers etc. Keep it simple.
But use two. One with an axe is fine for the slopes of Lenin, but for the walk from BC to C1 it's like a regular trek and two poles help your knees, help stability on loose scree and help with river crossings. There are some dangerously loose scree slopes above the section to C1 (i.e. rockfall) and also one dicey river crossing.
For Lenin I can understand you taking your own poles, but for Himalayan trips now I just usually buy a cheap pair in KTM or wherever and give them to porters/horsemen at the end of the trip. Saves lugging them home and you don't have to worry about losing or breaking a pricey name brand model bought in the high street.
