I use poles from REI - 3 section - metal - rubber tip for summer = spike for winter - small basket that stays on all the time- spring loaded - screw off top to make it a camera mount - and extremely light. The cost was around $50 each. My use is for coming down mainly. But for going up they help when it is not a scramble.
Just gave one to my wife to use for walking the dog when the road is very icy. So, I will be hitting REI to get another one.
