Update:

Tonight, we purchased 2 pair of trekking poles. We went with the Black Diamond brand as the Flicklock system is much easier then the twist and lock methods of other poles.

We will try the poles out to see how we like them tomorrow. We are leaving early in the morning for an overnight winter hike and camp. The weather should be perfect for this, it will be just below freezing during the day and about -10C (14F) overnight.
