It might be worth remembering that some of the majors also do CF trekking poles. We reviewed the Easton 3-section UL Carbon 3 trekking poles at
Note: many of the cottage UL poles are either 2-section, so they don't fit in a pack for air travel, or the handles are not all that good (personal opinion based on my own experience). The Easton pole has a good handle and collapses to fit inside a pack - but it is not really 'UL'. Light, yes.
