I use Black Diamonds with flick locks too. They are stronger than many of the "trekking" poles as mine are built for skiing. As such they are a bit heavier. I like being able to adjust for height for uphills vs descents. Mine double as shooting sticks.
Then I ski with them all winter.
I've thought of employing my Leki adjustable alpine touring ski poles as trekking poles. I've used them when snowshoeing in the past. I figured I could just take the baskets off and they might make fine trekking poles
