I am interested in any comment that members of this community have had using carbon fiber or composite ski poles as alternatives to the traditional 3 section or single section trekking poles. Right now, the end of the ski season, one can often find high quality poles for 1/3 the cost of comparable trekking poles. In fact, I just noted a pair of K2 50/50 graphite and fiberglass poles for $30 weighing 15 oz for the pair at 135cm at my local ski shop. For $30 what could one lose?
