I use Black Diamond expedition poles, easy to use in winter and with gloves on as its flik lock, i can disassemble them in seconds and store them inside my pack if necessary. After using them i disassemble them, clean them and spray them in WD40 to prevent rust and pro-long the life of them. Each one of the 3 main sections are replaceable in the event of damage, i bought BD trekking baskets for use in uk hills outside of winter conditions so that my snow baskets don't get damaged by rocks or worn down (extra £3)
They can be used for mountaineering, hillwalking and ski touring. I cannot recommend the poles highly enough, if i am on a hill i can get both of poles extended for use quicker than someone can do 1 twist lock pole, also if a pole breaks on a walk you can guarantee its a twist lock. Very strong, simple poles you will get years of use out of.
A note of caution with sizing, as the poles may be used for snow and crossing rivers/streams then it is always advisable to go for a larger size as even with baskets it will sink in to snow and the extra height can make a big difference crossing water features or boggy ground.
